US 11,232,808 B2 · Adjusting speed of human speech playback

Abstract

A system configured to vary a speech speed of speech represented in input audio data without changing a pitch of the speech. The system may vary the speech speed based on a number of different inputs, including non-audio data, data associated with a command, or data associated with the voice message itself. The non-audio data may correspond to information about an account, device or user, such as user preferences, calendar entries, location information, etc. The system may analyze audio data associated with the command to determine command speech speed, identity of person listening, etc. The system may analyze the input audio data to determine a message speech speed, background noise level, identity of the person speaking, etc. Using all of these inputs, the system may dynamically determine a target speech speed and may generate output audio data having the target speech speed.

Dependent claims

A computer-implemented method, comprising:

receiving input audio data representing a voice command;
determining an input speech speed corresponding to the input audio data;
determining output data responsive to the voice command;
determining first data associated with a user profile corresponding to the voice command, the first data representing an incoming communication request for the user profile;
determining a target output speed based at least in part on the input speech speed and the first data;
using the output data to generate output audio data representing output speech, the output speech corresponding to the target output speed;
and
causing a device to output the output audio data.

5 more elements

A system comprising:

at least one processor;
and
memory including instructions operable to be executed by the at least one processor to configure the system to:
receive input audio data representing a voice command;
determine an input speech speed corresponding to the input audio data;
determine output data responsive to the voice command;
determine quality data corresponding to an audio quality of the output data;
determine a target output speed based at least in part on the input speech speed and the quality data;
using the output data, generate output audio data representing output speech, the output speech corresponding to the target output speed;
and
cause a device to output the output audio data.
