This study investigates whether a computer assisted pronunciation training (CAPT) system can help young learners improve word-level pronunciation skills in English as a foreign language at a level comparable to that achieved through traditional teacher-led training. The pronunciation improvement of a group of learners of 11 years of age receiving…

Potato cannon velocity can be measured with a digitized microphone signal. A microphone is attached to the potato cannon muzzle, and a potato is fired at an aluminum target about 10 m away. Flight time can be determined from the acoustic waveform by subtracting the time in the barrel and time for sound to return from the target. The potato…

Poor classroom acoustics are impairing students' hearing and their ability to learn. However, technology has come up with a solution: tools that focus voices in a way that minimizes intrusive ambient noise and gets to the intended receiver--not merely amplifying the sound, but also clarifying and directing it. One provider of classroom audio…

Teachers represent the largest group of occupational voice users and have voice-related problems at a rate of over twice that found in the general population. Among teachers, music teachers are roughly four times more likely than classroom teachers to develop voice-related problems. Although it has been established that music teachers use their…

Using an exploratory case study approach, the language use of five bilingual special education teachers of English Language Learners (ELLs) with disabilities was examined. Audio tapes, classroom observations, and teacher interviews yielded data on the language used by the bilingual teachers. Data revealed information on the frequency of the use of…

With the rapid development of wireless networks and mobile technologies and the increasing adoption of mobile learning, the need for "anywhere, anytime and any device" access to information becomes more evident. This has influenced the design of learning objects. The small but developing literature on vodcasting indicates its potential…

Podcasting is the creation of audio or video files for use on iPods and other MP3 players. It allows the user to view or listen to downloadable files wherever or whenever desired. In higher education, podcasting is experiencing extraordinary growth. While a significant volume of literature exists both lauding and lamenting the incorporation of…

This study examines how bilingual family members use language choice and language alternation as a local scheme of interpretation to distinguish different and often contesting social identities in interaction. It is argued that the playful creation of oppositional identities in interaction relieves the speakers from responsibility and creates a…

In the summer of 2006, Open Borders Project/Proyecto Sin Fronteras, a small educational center in the heart of Latino North Philadelphia, sponsored a six-week program to teach teens from Philadelphia public schools how to plan and conduct interviews, edit audio files, and write the necessary preparatory material to produce short pieces about…

This study explores students' attitudes to the provision of formative feedback on academic work using audio files together with the ways in which students implement such feedback within their learning. Fifteen students received audio file feedback on written work and were subsequently interviewed regarding their utilisation of that feedback within…

A flexible surface disc device serves as the basis for the design of a computer operated multi-user shared hardware audio response system. The device employs a slow moving flexible, air supported surface in contact with a large number of heads. Relatively instantaneous distribution of audio from any portion of the disc to the users in accomplished…

A discussion of the problems of high-quality audio generation. (Author)

Described is a low cost cassette storage unit which can be easily constructed. Diagrams and a photograph of the finished unit are included. (STS)

A computer based dynamic orometer is described which was developed to study deaf speech and the visual-vocal linkage paralleling the auditory-vocal channel of hearing children. Preliminary results are reported for oral sensory-motor control, speech production, and acoustic findings. (Author/CL)

This paper introduces the idea of enhancing the audio presentation of a multimedia museum guide by using the PDA screen to travel throughout a fresco and identify the various details in it. During the presentation, a sequence of pictures is synchronized with the audio commentary, and the transitions among the pictures are planned according to…
