System and method for network bandwidth management for adjusting audio quality
Disclosed herein are systems, methods, and computer-readable storage devices for processing audio signals. An example system configured to practice the method receives audio at a device to be transmitted to a remote speech processing system. The system analyzes one of noise conditions, need for an enhanced speech quality, and network load to yield an analysis. Based on the analysis, the system determines to bypass user-defined options for enhancing audio for speech processing. Then, based on the analysis, the system can modify an audio transmission parameter used to transmit the audio from the device to the remote speech processing system. The audio transmission parameter can be one of an amount of coding, a chosen codec, an amount of coding, or a number of audio channels, for example.
1. A method comprising:
receiving, at a device and at a first time, audio to be transmitted to a remote speech processing system;
identifying an audio quality associated with the audio;
transmitting the audio to the remote speech processing system according to an audio transmission parameter which identifies a number of audio channels to use for transmitting the audio;
detecting, at the device and at a second time after the first time, a change in the audio quality;
modifying the audio transmission parameter based on the change in the audio quality, to yield a modified audio transmission parameter which identifies a new number of audio channels to use for transmitting addition audio; and
transmitting the additional audio to the remote speech processing system according to the modified audio transmission parameter.
2. The method of claim 1 , wherein the audio transmission parameter comprises one of an amount of coding and a chosen codec.
3. The method of claim 1 , wherein the audio transmission parameter further indicates data associated with coding.
4. The method of claim 1 , wherein the audio transmission parameter is further based on one of a user profile stored in a network and a battery level.
5. The method of claim 1 , wherein the change in the audio quality is caused by a network load.
6. The method of claim 1 , wherein modifying the audio transmission parameter further comprises:
determining a respective priority level for each of a plurality of audio channels from separate microphones; and
encoding each of the plurality of audio channels according to the respective priority level.
7. The method of claim 1 , wherein the audio comprises a voice of a user, the method further comprising:
tracking the voice of the user over time; and
adjusting a profile of the user upon detecting a change in the voices that exceeds a threshold.
8. A system comprising:
a processor; and
a computer-readable storage device storing instructions which when executed by the processor, cause the processor to perform operations comprising:
receiving, at a device and at a first time, audio to be transmitted to a remote speech processing system;
identifying an audio quality associated with the audio;
transmitting the audio to the remote speech processing system according to an audio transmission parameter which identifies a number of audio channels to use for transmitting the audio;
detecting, at the device and at a second time after the first time, a change in the audio quality;
modifying the audio transmission parameter based on the change in the audio quality, to yield a modified audio transmission parameter which identifies a new number of audio channels to use for transmitting addition audio; and
transmitting the additional audio to the remote speech processing system according to the modified audio transmission parameter.
9. The system of claim 8 , wherein the audio transmission parameter comprises one of an amount of coding and a chosen codec.
10. The system of claim 8 , wherein the audio transmission parameter further indicates data associated with coding.
11. The system of claim 8 , wherein the audio transmission parameter is further based on one of a user profile stored in a network and a battery level.
12. The system of claim 8 , wherein the change in the audio quality is caused by a network load.
13. The system of claim 8 , wherein modifying the audio transmission parameter further comprises:
determining a respective priority level for each of a plurality of audio channels from separate microphones; and
encoding each of the plurality of audio channels according to the respective priority level.
14. The system of claim 8 , wherein the audio comprises a voice of a user, the operations further comprising:
tracking the voice of the user over time; and
adjusting a profile of the user upon detecting a change in the voices that exceeds a threshold.
15. A computer-readable storage device storing instructions which when executed by a processor, cause the processor to perform operations comprising:
receiving, at a device and at a first time, audio to be transmitted to a remote speech processing system;
identifying an audio quality associated with the audio;
transmitting the audio to the remote speech processing system according to an audio transmission parameter which identifies a number of audio channels to use for transmitting the audio;
detecting, at the device and at a second time after the first time, a change in the audio quality;
modifying the audio transmission parameter based on the change in the audio quality, to yield a modified audio transmission parameter which identifies a new number of audio channels to use for transmitting addition audio; and
transmitting the additional audio to the remote speech processing system according to the modified audio transmission parameter.
16. The computer-readable storage device of claim 15 , wherein the audio transmission parameter comprises one of an amount of coding and a chosen codex.
17. The computer-readable storage device of claim 15 , wherein the audio transmission parameter further indicates data associated with coding.
