System and method for configuring voice synthesis
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 for controlling a spoken dialog system, the method comprising:
based on a listening environment and at least one other parameter associated with at least one of a connection characteristic, a spectral difference, or a bandwidth availability, selecting an approach from a plurality of approaches for presenting synthesized speech in the listening environment;
presenting synthesized speech according to the selected approach; and
based on natural language input received from a user indicating 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.
2. The method of claim 1 , wherein the at least one other parameter further comprises at least one of physiological aspects, psychological aspects of perception, and historical data.
3. The method of claim 1 , wherein selecting an approach further comprises matching the listening environment to at least one entity associated with an approach for presenting the synthesized speech.
4. The method of claim 3 , wherein the at least one entity comprises phonemes or phoneme classes.
5. The method of claim 1 , wherein selecting an approach further comprises specifying phonemes for use in presenting the synthesized speech.
6. A system for generating speech, the system comprising:
a suggestion module that receives environmental input associated with a listening environment and generates a first suggestion of an approach for presenting speech in the listening environment;
a historical suggestion module that receives the environmental input and generates a second suggestion for presenting speech in the listening environment based on historical data for presenting speech in the listening environment;
a selection module that receives at least the first and second suggestion and selects the approach for presenting the speech; and
a speech synthesis module that presents speech in the listening environment based at least in part on the selected approach.
7. The system of claim 6 , further comprising:
a modification module that receives the selected approach and a separate input and modifies the selected approach based on the input and outputs a modified selection; and wherein the speech synthesis module receives the modified selection and presents speech in the listening environment based on the modified selection.
8. The system of claim 7 , wherein the separate input comprises input from a user.
9. The system of claim 8 , wherein the user input requests at least one of the following speech characteristics: lower, higher, softer, louder, slower, faster, higher pitched, or lower pitched.
10. The system of claim 7 , wherein the separate input is an instruction from a user to modify synthesized speech.
11. The system of claim 7 , wherein the input to the modification module results in different phonemes being selected for speech synthesis than would be selected based on output from the selection module.
12. A computer-implemented method of synthesized speech, the method comprising:
receiving environmental input and generating a first suggestion for a first approach to present speech in a listening environment;
receiving the environmental input and generating a second suggestion for a second approach to present speech in the listening environment based on historical data associated with presenting speech in the listening environment;
receiving the suggestion of the first approach and the suggestion of the second approach and generating a selection of an approach based on the first suggestion and second suggestion;
receiving separate input regarding how to present the speech;
modifying the selected approach based on the separate input; and
presenting speech in the listening environment based on the modified selected approach.
13. The method of claim 12 , wherein the separate input is user input.
14. The method of claim 12 , further comprising:
selecting phonemes for presenting the speech based on the modified selected approach.
