Voice privacy for far-field voice control devices that use remote voice services

The system of claim 22, further comprising:

• a controller configured to perform operations comprising:
• receiving an instruction from an application;
• and
• selecting one or more modules of the set of modules based on the instruction.

The system of claim 22, further comprising:

• a third module of the set of modules configured to perform operations comprising:
• generating a second voice data based on the input audio;
• and
• providing the second voice data as input to a local ASR module for generating speech recognition data.

The system of claim 22, wherein the separating of the input audio into the first data and the second data comprises:

• determining whether an echo is present in the input audio based on a reference signal;
• removing an echo from the input audio based on the reference signal, in response to determining that an echo is present in the input audio;
• demixing the first data and the second data from the input audio;
• and
• increasing a gain of the first data.

An integrated circuit, comprising:

• a first module of a set of modules configured to perform operations comprising:
• generating voice data based on an input audio;
• anonymizing the voice data by applying a first audio transformation;
• and
• transmitting the anonymized voice data to a first remote automatic speech recognition (ASR) module for generating speech recognition data.

The integrated circuit of claim 25, further comprising:

• a controller configured to perform operations comprising:
• receiving an instruction from an application;
• and
• selecting one or more modules of the set of modules based on the instruction.

The integrated circuit of claim 25, further comprising:

• a third module of the set of modules configured to perform operations comprising:
• generating a second voice data based on the input audio;
• and
• providing the second voice data as input to a local ASR module for generating speech recognition data.

The integrated circuit of claim 25, wherein the separating of the input audio into the first data and the second data comprises:

• determining whether an echo is present in the input audio based on a reference signal;
• removing an echo from the input audio based on the reference signal, in response to determining that an echo is present in the input audio;
• demixing the first data and the second data from the input audio;
• and
• increasing a gain of the first data.

A method, comprising:

• receiving an input audio and a reference signal;
• generating, using a first module, voice data based on the input audio and the reference signal;
• anonymizing, using the first module, the voice data by applying a first audio transformation;
• and
• transmitting, using the first module, the anonymized voice data to a first remote automatic speech recognition (ASR) module for generating speech recognition data.

The method of claim 21, wherein the separating of the input audio into the first data and the second data comprises:

• removing, using the second module, the reference signal from the input audio;
• demixing, using the second module, the first data and the second data from the input audio;
• and
• increasing, using the second module, a gain of the first data.

A system, comprising:

• a first module of a set of modules configured to perform operations comprising:
• separating an input audio into a first data and a second data;
• anonymizing the first data by applying a first audio transformation to the first data;
• generating an anonymized audio data by combining the anonymized first data and the second data;
• and
• transmitting the anonymized audio data to a first remote ASR module for generating speech recognition data.
