System and method for configuring voice synthesis based on environment
View Patent ↗Systems and methods for providing synthesized speech in a manner that takes into account the environment where the speech is presented. A method embodiment includes, based on a listening environment and at least one other parameter associated with at least one other parameter, selecting an approach from the plurality of approaches for presenting synthesized speech in a listening environment, presenting synthesized speech according to the selected approach and based on natural language input received from a user indicating that an inability to understand the presented synthesized speech, selecting a second approach from the plurality of approaches and presenting subsequent synthesized speech using the second approach.
1. A method comprising:
generating synthesized speech from input text using a historical speech template;
playing the synthesized speech;
receiving from a user an indication of inability to understand the synthesized speech;
receiving an environmental input indicating environmental conditions near the user;
selecting, based on the environmental input, an environmental speech template;
generating, via a processor, modified synthesized speech from the input text using the environmental speech template; and
responsive to receiving the indication of inability to understand the synthesized speech, playing the modified synthesized speech.
2. The method of claim 1 , further comprising recording the modified synthesized speech in a suggestion database.
3. The method of claim 2 , wherein the suggestion database comprises environmental speech templates based on one of a connection type, a bandwidth available, and an abnormal human perception.
4. The method of claim 1 , wherein the modified synthesized speech comprises phonemes modified according to the environmental speech template.
5. The method of claim 1 , wherein the selecting, based on the environmental input, the environmental speech template further comprises matching the environmental input to a plurality of environmental variables in a matrix.
6. The method of claim 5 , wherein a match is identified when a spectral difference between the environmental input and a property of an entity exceeds a threshold.
7. The method of claim 6 , wherein the spectral difference is frequency weighted based on human auditory perception.
8. A system comprising:
a processor; and
a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
generating synthesized speech from input text using a historical speech template;
playing the synthesized speech;
receiving from a user an indication of inability to understand the synthesized speech;
receiving an environmental input indicating environmental conditions near the user;
selecting, based on the environmental input, an environmental speech template;
generating modified synthesized speech from the input text using the environmental speech template; and
responsive to receiving the indication of inability to understand the synthesized speech, playing the modified synthesized speech.
9. The system of claim 8 , the computer-readable storage medium having additional instructions stored which, when executed by the processor, result in the operations further comprising recording the modified synthesized speech in a suggestion database.
10. The system of claim 9 , wherein the suggestion database comprises environmental speech templates based on one of a connection type, a bandwidth available, and an abnormal human perception.
11. The system of claim 8 , wherein the modified synthesized speech comprises phonemes modified according to the environmental speech template.
12. The system of claim 8 , wherein the selecting, based on the environmental input, the environmental speech template further comprises matching the environmental input to a plurality of environmental variables in a matrix.
13. The system of claim 12 , wherein a match is identified when a spectral difference between the environmental input and a property of an entity exceeds a threshold.
14. The system of claim 13 , wherein the spectral difference is frequency weighted based on human auditory perception.
15. A non-transitory computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:
generating synthesized speech from input text using a historical speech template;
playing the synthesized speech;
receiving from a user an indication of inability to understand the synthesized speech;
receiving an environmental input indicating environmental conditions near the user;
selecting, based on the environmental input, an environmental speech template;
generating modified synthesized speech from the input text using the environmental speech template, to yield modified synthesized speech; and
responsive to receiving the indication of inability to understand the synthesized speech, playing the modified synthesized speech.
16. The non-transitory computer-readable storage device of claim 15 , the non-transitory computer-readable storage device having additional instructions stored which, when executed by the computing device, result in the operations further comprising recording the modified synthesized speech in a suggestion database.
17. The non-transitory computer-readable storage device of claim 16 , wherein the suggestion database comprises environmental speech templates based on one of a connection type, a bandwidth available, and an abnormal human perception.
18. The non-transitory computer-readable storage device of claim 15 , wherein the modified synthesized speech comprises phonemes modified according to the environmental speech template.
19. The non-transitory computer-readable storage device of claim 15 , wherein the selecting, based on the environmental input, the environmental speech template further comprises matching the environmental input to a plurality of environmental variables in a matrix.
20. The non-transitory computer-readable storage device of claim 19 , wherein a match is identified when a spectral difference between the environmental input and a property of an entity exceeds a threshold.
