    摘要： Embodiments of the present invention use one or more audible tones to communicate metadata during a transfer of an audio file. Embodiments of the present invention communicate an audio file from a speaker in a recording device (e.g., a recordable book, toy, computing device) to a microphone in a receiving device. The audio file is transferred by audibly broadcasting the audio file content. The audio file may be a recording made by the user (e.g., the user singing a song, a child responding to a storybook prompt intended to elicit a response). The file transfer process uses one or more audible tones, such as dual-tone multi-frequency signaling (“DTMF”) tones to communicate metadata associated with the audio file. Audible tones may also be used to communicate commands that delineate the beginning and/or end of a file broadcast.

    摘要： The present invention relates to a method of evaluating intelligibility of a degraded speech signal received from an audio transmission system conveying a reference speech signal. The method comprises sampling said signals into reference and degraded signal frames, and forming frame pairs by associating reference and degraded signal frames with each other. For each frame pair a difference function representing disturbance is provided, which is then compensated for specific disturbance types for providing a disturbance density function. Based on the density function of a plurality of frame pairs, an overall quality parameter is determined. The method provides for compensating the overall quality parameter for the effect that the assessment of intelligibility of CVC words is dominated by the intelligibility of consonants.

    摘要： A memory controller includes an encoder, a modulator, and a demodulator. A nonvolatile memory includes memory cells, each programmable to one of three or more levels. According to first encoded data, the modulator programs a first subset of the memory cells to a first of the levels and a second subset of the memory cells to a second of the levels. Measurable values of the first subset are characterized by a first probability density function having a first width. Measurable values of the second subset are characterized by a second probability density function having a second width. The first width is greater than the second width. The encoder generates the first encoded data based on input data such that the first subset is smaller than the second subset. The demodulator is configured to output second encoded data in response to measurable values of the memory cells.
