A system for processing voice requests includes a voice assistant manager and a plurality of voice assistants. The voice assistant manager detects a wake word in an utterance and communicates the utterance to a voice assistant of the plurality of voice assistants. In some embodiments, the voice assistant may verify the detected wake word and communicate with a cloud service, which may also verify the detected wake word and generate a response to the utterance. In some embodiments, the voice assistant manager may activate or deactivate one or more of the voice assistants.

System for processing voice requests including wake word verification

A method for processing voice input is disclosed. The method may be performed by a device including a voice assistant manager and a plurality of voice assistants. In some embodiments, the method includes receiving an utterance from a user, detecting a category of the utterance, and communicating the utterance to a selected voice assistant of the plurality of voice assistants. The selected voice assistant may be associated with the detected category. In some embodiments, the selected voice assistant may generate a response to utterance, and the response may be output to the user.

Method and system for selecting a voice assistant

A second wake word detector, at a media-playback device, that plays audio (or other) content to a device, such as a voice-enabled device, detects false wake words in the audio content. The second wake word detector analyzes the audio stream to determine if the audio stream contains any audio that sounds like the wake word. If so, the second wake word detector can generate one of a plurality of instructions that describes the time period, within the audio content, in which the false wake word was encountered. The instruction can cause a first wake word detector to assume one of a plurality of configurations. The media-playback device can then instruct or inform the voice-enabled device of the presence of the false wake word. In this way, the wake word detector, at the voice-enabled device, is not activated to receive the false wake word or ignores the wake word.

Variable wake word detectors

The present disclosure relates generally to speech processing. Humans change their speech patterns in noisy environments. The systems and devices described herein can compensate for noisy environments to be more human-like. Thus, the configurations and implementations herein can determine a sound profile for the sound environment where the user is listening. Based on the sound profile, the devices can determine a transform to apply to output speech from the device. This transform is applied to the wake word, speech recognition, and to the output speech to compensate for the noise level of the environment by mimicking the Lombard effect.

Text-to-speech and speech recognition for noisy environments

Apparatus, methods and computer-readable medium are provided for processing wind noise. Audio input is processed by receiving an audio input. A wind noise level representative of a wind noise at the microphone array is measured using the audio input and a determination is made, based on the wind noise level, whether to perform either (i) a wind noise suppression process on the audio input on-device, or (ii) the wind noise suppression process on the audio input on-device and an audio reconstruction process in-cloud.

Noise suppressor

An electronic device displays a first icon comprising a shape. While displaying the first icon, the device receives a voice command corresponding to a request for media content from the application. In response to, and while receiving, the voice command, the device dynamically animates the first icon, including distorting a radius of a portion of the shape in accordance with a direction of the voice command. The dynamic animation indicates that the electronic device is in a first state. After the voice command is completed, the device displays an indication that the device is in a second state that is distinct from the first state.
