Abstract: Embodiments of the disclosure provide for adapting speech recognition confidence scores to one or more users based on expect response(s). Some embodiments, receive input speech and generate, based on the input speech and using a recognition algorithm, a recognition hypothesis. The recognition hypothesis may comprise at least one pairing comprising a word and an initial confidence score associated with the word. Some embodiments, determine whether the recognition hypothesis matches an expected response based at least in part on comparing the word to a corresponding word in an expected response. Some embodiments, in response to determining that the recognition hypothesis matches the expected response, updates statistical data associated with the word.

Abstract: Embodiments of the disclosure provide for adapting word pronunciations in a speech recognition system to a user(s) based on expected responses. Some embodiments receive input speech and generate a recognition hypothesis for the input speech. The search algorithm may be informed by a pronunciation dictionary. The recognition hypothesis may comprise a sequence of one or more words. Some embodiments compare the recognition hypothesis with at least one expected response to determine if the recognition hypothesis matches the at least one expected response. Some embodiments generate a phoneme sequence for each word in the recognition hypothesis. Some embodiments after determining that the recognition hypothesis matches the at least one expected response, update a set of phoneme sequences in the pronunciation dictionary associated with at least one word of the recognition hypothesis.

Abstract: A speech recognition system used in a workflow receives and analyzes speech input to recognize and accept a user's response to a task. Under certain conditions, a user's response might be expected. In these situations, the expected response may modify the behavior of the speech recognition system to improve recognition accuracy. For example, if the hypothesis of a user's response matches the expected response then there is a high probability that the user's response was recognized correctly. An expected response may include expected words and wildcard words. Wildcard words represent any recognized word in a user's response. By including wildcard words in the expected response, the speech recognition system may make modifications based on a wide range of user responses.

Abstract: A speech recognition system receives and analyzes speech input from a user in order to recognize and accept a response from the user. Under certain conditions, information about the response expected from the user may be available. In these situations, the available information about the expected response is used to modify the behavior of the speech recognition system by taking this information into account. The modified behavior of the speech recognition system comprises adjusting the rejection threshold when speech input matches the predetermined expected response.

Abstract: A speech recognition system used for hands-free data entry receives and analyzes speech input to recognize and accept a user's response. Under certain conditions, a user's response might be expected. In these situations, the expected response may modify the behavior of the speech recognition system to improve performance. For example, if the hypothesis of a user's response matches the expected response then there is a high probability that the user's response was recognized correctly. This information may be used to make adjustments. An expected response may include expected response parts, each part containing expected words. By considering an expected response as the concatenation of expected response parts, each part may be considered independently for the purposes of adjusting an acceptance algorithm, adjusting a model, or recording an apparent error. In this way, the speech recognition system may make modifications based on a wide range of user responses.

Abstract: A communication component modifies production of an audio waveform at determined modification segments to thereby mitigate the effects of a delay in processing and/or receiving a subsequent audio waveform. The audio waveform and/or data associated with the audio waveform are analyzed to identify the modification segments based on characteristics of the audio waveform and/or data associated therewith. The modification segments show where the production of the audio waveform may be modified without substantially affecting the clarity of the sound or audio. In one embodiment, the invention modifies the sound production at the identified modification segments to extend production time and thereby mitigate the effects of delay in receiving and/or processing a subsequent audio waveform for production.

Abstract: A system and method for supplying power to a headset, and for transmitting multiple signals generated in the headset to a terminal using frequency division multiplexing. An audio signal and a carrier signal are generated in the terminal and summed together to form a composite uplink signal. The composite uplink signal is provided to a headset over a first physical channel. At the headset, the audio and carrier signals are separated, and the carrier signal is used to generate power in the headset. Signals generated by a plurality of acoustic sensors in the headset are combined using frequency division multiplexing to generate a composite downlink signal, which is transmitted to the terminal over a second physical channel. One or more carrier signals used to generate the composite downlink signal are provided by either a carrier source in the headset, or by recovering the carrier signal from the composite uplink signal.

Abstract: A power delivery method and system for powering a headset. A power signal is combined with an audio signal to form a composite signal that is communicated over a shared channel to the headset. The power signal is generated by modulating a carrier signal with a modulation signal. The modulation signal is derived from the amplitude of the audio signal so that the peak levels of the composite signal do not exceed the maximum allowable output of an audio I/O circuit driving the headset.
