Abstract:
This paper investigates the impact of touch-tone IVR design styles on user behavior. The design of the touch-tone IVR systems is a critical component of delivering customer service. A well-designed system allows the customers to accomplish their goals and sets a positive tone to their interaction with the organization. Four design styles were considered: Action-Specific Object, Action-General Object, Specific Object, and General Object. Three user behaviors were considered: Cut-Through, Full Menu, and Beyond Full Menu. A usability study was conducted to quantify the impact of design styles on user behavior. Results indicate that design style does impact user behavior. The Action-Specific Object style produced the most Cut-Through behaviors and the fewest Beyond Full Menu behaviors compared to the other design styles. The results from this paper suggest that the interface design style should match the customer's mental model.

Abstract:
While interactive voice response (IVR) systems were rapidly making their way into the workplace, speech scientists were working hard to improve the performance of automatic speech recognition (ASR) systems to foster their acceptance among potential customers. In the last five years, great strides have been made in this regard, and the commercial use ASR is on the rise. The purpose of this panel is to explore the impact that ASR is (or is not) having on the design of IVR systems that were envisioned originally to operate solely via touch-tone input.

Abstract:
Voice-messaging (also called voice mail) is a computer-based technology that uses a standard touch-tone telephone for input and retrieval. Because of its ability to enhance communication, voice mail is a powerful communication tool. Voice mail systems allow users to access their messages from any touch-tone telephone, twenty-four hours a day, distribute one message to many recipients, forward messages with covering remarks to other users, mark a message for future delivery, and create personal greetings. In addition, many of the voice mail systems currently available offer interfaces to electronic mail and fax communication—thereby providing a complete communication management facility. Although much has been written about the use of voice messaging, little is known about how voice messaging is used by faculty at institutions of higher education. The communication needs of this group differ in crucial ways from business organizations and even from the needs of their own administrators. While faculty have as strong a need for communication and interaction with their students and colleagues, their varied hours often prevent them from being available to do so. This article describes the unique communication needs of academicians and how innovative use of voice mail can address these needs. By creating a virtual office, voice mail can serve as a solution to: the conflict many academicians have between being in the office for students and conducting research; the frustration inherent in trying to contact committee members and colleagues; receiving messages meant for someone else; and extended absences from campus that put faculty out of touch with students and others.

Abstract:
AbstractRecreational noise–induced hearing loss (RNIHL) is a major health issue and presents a huge economic burden on society. Exposure to loud music is not considered hazardous in our society because music is thought to be a source of relaxation and entertainment. However, there is evidence that regardless of the sound source, frequent exposure to loud music, including through personal audio systems (PAS), can lead to hearing loss, tinnitus, difficulty processing speech, and increased susceptibility to age-related hearing loss.Several studies have documented temporary threshold shifts (TTS) (a risk indicator of future permanent impairment) in subjects that listen to loud music through their PAS. However, there is not enough information regarding volume settings that may be considered to be safe. As a primary step toward quantifying the risk of RNIHL through PAS, we assessed changes in auditory test measures before and after exposure to music through the popular iPod Touch device set at various volume levels.This project design incorporated aspects of both between- and within-subjects and used repeated measures to analyze individual groups.A total of 40 adults, aged 18–31 years with normal hearing were recruited and randomly distributed to four groups. Each group consisted of five males and five females.Subjects underwent two rounds of testing (pre- and postmusic exposure), with a 30-min interval, where they listened to a playlist consisting of popular songs through an iPod at 100%, 75%, 50%, or 0% volume (no music). Based on our analysis on the Knowles Electronic Manikin for Acoustic Research, with a standardized 711 coupler, it was determined that listening to the playlist for 30 min through standard earbuds resulted in an average level of 97.0 dBC at 100% volume, 83.3 dBC at 75% volume, and 65.6 dBC at 50% volume. Pure-tone thresholds from 500–8000 Hz, extended high-frequency pure tones between 9–12.5 kHz, and distortion product otoacoustic emissions (DPOAE) were obtained before and after the 30-min music exposure. Analysis of variance (ANOVA) was performed with two between-subjects factors (volume and gender) and one within-subjects factor (frequency). Change (shift) in auditory test measures was used as the outcome for the ANOVA.Results indicated significant worsening of pure-tone thresholds following music exposure only in the group that was exposed to 100% volume at the following frequencies: 2, 3, 4, 6 and 8 kHz. DPOAEs showed significant decrease at 2000 and 2822 Hz, also only for the 100% volume condition. No significant changes were found between pre- and postmusic exposure measures in groups exposed to 75%, 50%, or 0% volume conditions. Follow-up evaluations conducted a week later indicated that pure-tone thresholds had returned to the premusic exposure levels.These results provide quantifiable information regarding safe volume control settings on the iPod Touch with standard earbuds. Listening to music using the iPod Touch at 100% volume setting for as little as 30 min leads to TTS and worsening of otoacoustic emissions, a risk for permanent auditory damage.

Abstract:
DTMF (Dual Tone Multi Frequency) is a system of signal tones used for telecommunications. DTMF uses two tones to represent each key on the touch pad. DTMF data transfer technique has advantages such as high reliability, constant speed, and high signal to noise ratio, low cost and optimal utilization of existing resources. These features make DTMF an attractive Data Transfer Technique. It finds application in home and car security systems, robot control, SMS and voice call controlled industrial applications. In this paper, we discuss the use of DTMF data transfer in a voice call to control a toy car. Cell phone 1(CP 1), which is at user end, makes a call to cell phone 2(CP 2) at the machine end and establishes a connection. A key is pressed at the user side. Two tones corresponding to one key are encoded and sent through the cell phone network. Both tones are tapped through the earphone jack of cell phone at machine end and are decoded. The output is fed to a Micro-controller. The Micro-controller is connected to the remote control unit of the toy car, which in turn controls the motion of the car. The car moves in various directions according to the key pressed user. The electronic circuit is divided into 2 parts. The transmitter side consisting of Cell phone 1 with an inbuilt encoder and the receiver side consisting of Cell Phone 2, 8870 DTMF decoder and Atmega 16 micro-controller. The programming has been carried out on AVR Bascom®.

Abstract:
To determine the effectiveness of Touch-Tone or ASR (Automatic Speech Recognition) Directory Services, three studies were conducted. Specifically, Roe and Salahi's (1984) search algorithm, based on a Hidden Markov Probability Model, was evaluated. The initial study assessed the algorithm's ability to locate a targetted directory listing from correctly or incorrectly spelled TT inputs. The second study determined the generalizability of the original study, and the third study evaluated the accuracy of the algorithm for voiced-in listings that were interpreted by a speech recognizer. The names were sampled from a 1,450-name AT&T Information Systems data base. For TT inputs, results from the first two studies were similar; overall, the algorithm located 93.5% of the targetted names despite the fact that two thirds of the names were purposely spelled incorrectly. 100% of the correctly spelled names were located. For voice inputs, results showed that the algorithm located 89.9% of the targetted names. These results attest to the fact that this algorithm is highly effective at locating targetted directory listings regardless of spelling errors. The high degree of accuracy is especially impressive in light of the fact that each TT key is associated with 3 or 4 letters of the alphabet and that each voice input may be interpreted as any of the 26 letters of the alphabet.

Abstract:
Abstract We often rely on our sense of vision for understanding the spatial location of objects around us. If vision cannot be used, one must rely on other senses, such as hearing and touch, in order to build spatial representations. Previous work has found evidence of a leftward spatial bias in visual and tactile tasks. In this study, we sought evidence of this leftward bias in a non-visual haptic object location memory task and assessed the influence of a task-irrelevant sound. In Experiment 1, blindfolded right-handed sighted participants used their non-dominant hand to haptically locate an object on the table, then used their dominant hand to place the object back in its original location. During placement, participants either heard nothing (no-sound condition) or a task-irrelevant repeating tone to the left, right, or front of the room. The results showed that participants exhibited a leftward placement bias on no-sound trials. On sound trials, this leftward bias was corrected; placements were faster and more accurate (regardless of the direction of the sound). One explanation for the leftward bias could be that participants were overcompensating their reach with the right hand during placement. Experiment 2 tested this explanation by switching the hands used for exploration and placement, but found similar results as Experiment 1. A third Experiment found evidence supporting the explanation that sound corrects the leftward bias by heightening attention. Together, these findings show that sound, even if task-irrelevant and semantically unrelated, can correct one’s tendency to place objects too far to the left.

Abstract:

Touch-tone interfaces are today widely used in help-centers and support services. Studies have shown that interfaces like these have many limitations and are therefore hard to design. MVAS is a voicemail interface using touch- tone input for navigation. Today, shortcomings in the interface limit the users’ ability to use the functionality in a satisfying way. This thesis describes a mainly qualitative study which evaluates and tests the interface of MVAS to come up with how the interface should be designed to be easier to use. The results show that the usability of MVAS is poor but the functionality of the same is both impressive and appreciated. The suggested redesign of the system, based on the identified usability problems, considers both the interaction model used in the interface as well as the conformity to the set of heuristics used in the evaluation. The proposed redesign keeps all the functionality in the system intact and also makes the functionality more explicit through improving the usability. A more explicit structure will facilitate usage of a larger portion of the functionality. However, the limitation of the key-pad affects the redesign so the most favorable design is unreachable. If the interaction model is changed or furthered developed to allow speech input the limitations experienced with the current redesign will diminish and a higher degree of usability can be reached.

Abstract:
What are the strengths and weaknesses of computer-based and other automated methods of detecting depression? Two promising technologies make use of the Internet and speech recognition. Whatever technology is used, each method needs to be assessed rigorously using the same high standards that have been applied to pencil-and-paper tests. We are in the midst of a technological revolution that inevitably will transform psychiatric clinical practice. A consensus for routine depression screening is building, and at the same time methods by which it could be accomplished are emerging. The hope is that the right technology can provide an easy, inexpensive, valid, and reliable public health approach to depression screening. Computerized assessment is well accepted in diverse fields, and the use of Internet-based survey technology has grown exponentially. Issues regarding the strengths and limitations of computerized assessments are addressed regularly in the literature. For example, such assessments have been shown to improve data quality while at the same time reducing cost as well as the time to score, analyze, and report results. Increasingly, as depressive disorders have been recognized as highly prevalent with significant morbidity, multiple screeners using an array of technological advances have been developed (Table 8.1 lists selected studies). This chapter will review the technologies that are currently available for automated depression screening and will discuss them in terms of criteria that should dictate their adoption. The growing list of technologies can be classified on several dimensions. Perhaps themostimportant of these isadaptivevs.non-adaptive. Inanadaptive technology pioneered by the Educational Testing Service, a computer, using a preprogrammed algorithm, decides which question to ask next given the responses so far. Paper-and-pencil is the classical non-adaptive technology— everyone gets the same paper with the same questions in the same order. Technological modality is a second dimension. Currently available technologies include the phone, the Internet, and hand-held electronic devices. The phone can be split into several groups, including agent: computer-assisted telephone interview (CATI), speech recognition, and touch-tone. Phone can also be classified as inbound (the patient initiates the call to a toll-free number) or outbound (the system initiates the call).
