摘要： A device, system and method for audio transmission quality assessment that occurs during the transmission. A transmission channel such as the internet is used to transmit speech that is spoken by a human speaker, captured at a first end, and transmitted over the transmission channel for reproduction at a second end. The processors at each end of the transmission channel are configured to determine one or more characteristics of the speech such as phonemes. The phonemes are transmitted over a backchannel of the transmission channel to a processor that compares the speech characteristics that were determined at both ends of the call. The participants are notified of a transmission problem that has had an effect on the intelligibility of the speech that was reproduced at the far end if the comparison does not meet a predetermined quality metric.

摘要： An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular example, the audio demonstration kit includes a paper speaker and instructions. The paper speaker includes a backplate, a suspension, and a diaphragm cut from a single sheet of paper. The demonstration kit may feature an amplifier that is configurable to accommodate various hardware additions as a child is ready for more progressively challenging construction. For example, the amplifier of an example allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an example is synchronized with the strobe light and a moveable platform to create the impression of that jiggling figures attached to the table are dancing. Interfaces with smart phone, recording, and other technologies further enhances and encourages the learning experience.
