  • Patent number: 10354649
    Abstract: Techniques for altering audio being output by a voice-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the voice-controlled device. For instance, a voice-controlled device may output audio within an environment using a speaker of the device. While outputting the audio, a microphone of the device may capture sound within the environment and may generate an audio signal based on the captured sound. The device may then analyze the audio signal to identify speech of a user within the signal, with the speech indicating that the user is going to provide a subsequent command to the device. Thereafter, the device may alter the output of the audio (e.g., attenuate the audio, pause the audio, switch from stereo to mono, etc.) to facilitate speech recognition of the user's subsequent command.

During subsequent audio playback, an imager captures images of at least a portion of the listener. When the listener has moved to a position that is different from a previous position, one or more audio parameters are adjusted for at least one channel in the multi-channel audio system in order to reposition the initial or previous optimal listening position to the current position of the listener.

  • Patent number: 10236850
    Abstract: A circuit and method is disclosed for filtering an audio signal. The circuit has a first quadrature source and multipliers for multiplying the input signal by the I and Q outputs of the quadrature source. The multiplied inputs are then passed through a pair of low pass filters, which may have an adjustable Q factor. The outputs of the low pass filters are then multiplied in a second pair of multipliers by the I and Q outputs, respectively, of a second quadrature source, which will typically be of the same frequency, but different amplitude and phase, of the first quadrature source. The twice-multiplied signals are then summed by an adder to provide an output signal. The circuit may be modified to include a companding circuit between the low pass filters and the second pair of multipliers that determines the amplitude of the input signal, filters it, and compands the signal in a compandor. The compandor may have adjustable parameters.

The speech recognition device includes a trigger generation unit for generating a trigger signal on the basis of at least mouth movement and a speech recognition unit which extracts a sound signal on the basis of the trigger signal and starts speech recognition for speech in the extracted sound signal. When the trigger generation unit is generating a trigger signal solely on the basis of opening of the mouth, the trigger generation unit generates the trigger signal so as to precede the opening of the mouth by a predetermined period. Alternatively, when the trigger generation unit is generating a trigger signal on the basis of opening of the mouth and changes in eye orientation, the trigger generation unit generates the trigger signal from the moment any of the above occurs.

  • Patent number: 9689960
    Abstract: The systems, devices, and processes described herein may identify a beam of a voice-controlled device that is directed toward a reflective surface, such as a wall. The beams may be created by a beamformer. An acoustic echo canceller (AEC) may create filter coefficients for a reference sound. The filter coefficients may be analyzed to identify beams that include multiple peaks. The multiple peaks may indicate presence of one or more reflective surfaces. Using the amplitude and the time delay between the peaks, the device may determine that it is close to a reflective surface in a direction of the beam.

  • Patent number: 9626986
    Abstract: The invention relates to a background noise estimator and a method therein, for supporting sound activity detection in an audio signal segment. The method comprises reducing a current background noise estimate when the audio signal segment is determined to comprise music and the current background noise estimate exceeds a minimum value. This is to be performed when an energy level of an audio signal segment is more than a threshold higher than a long term minimum energy level, lt_min, which is determined over a plurality of preceding audio signal segments, or, when the energy level of the audio signal segment is less than a threshold higher than lt_min, but no pause is detected in the audio signal segment.

  • Patent number: 9544684
    Abstract: An example information processing device determines a sound input to a microphone. The information processing device includes an obtaining section, a mean amplitude calculation section, and a determination section. The obtaining section obtains data of a sound detected by the microphone. For a sound of a predetermined determination segment, the mean amplitude calculation section calculates a mean amplitude, which is an average amplitude, for each of a plurality of partial segments included in the determination segment. The determination section determines whether or not the sound input to the microphone is a predetermined type of a sound (e.g., a sound made by breath blowing) based on the mean amplitudes for the partial segments.
