US Patent 10176809 Customized compression and decompression of audio data

Systems and methods for compressing and decompressing audio data are described. A server may receive input audio data corresponding to a spoken utterance from a speech-controlled device. The server performs speech processing on the input audio data to determine a spoken command and spoken solicited content. The server may then communication with a device associated with an application to obtain output audio data. The server may compress the output audio data by removing portions of audio data therefrom at regular intervals (e.g., milliseconds). The server may then send the compressed output audio data and instructions for decompressing the compressed output audio data to the speech-controlled device. Further, a speech-capturing device may also compress audio data corresponding to an utterance. The speech-capturing device may compress based on various factors, including the speech characteristics of the speaking user.
