Abstract

Systems and methods for vocal keyword training from text are provided. In one example method, text is received via keyboard or a touch screen. The text can include one or more words of language known to a user. The received text can be compiled to generate a signature. The signature can embody a spoken keyword and include a sequence of phonemes or a triphone. The signature can be provided as an input to automatic speech recognition (ASR) software for subsequent comparison to an audible input. In various embodiments, a mobile device receives the audible input and the text, and at least one of the compiling and ASR functionality is distributed to a cloud-based system.

Claims

1. A method for vocal keyword training from text, the method comprising:

receiving the text;

compiling, using one or more hardware processors, the text to generate a signature, the signature embodying a spoken keyword; and

storing the signature for comparison to an audible input.

2. The method of claim 1, wherein the text includes one or more words of a pre-selected language.

3. The method of claim 1, wherein the text includes a keyword selected from a pre-determined list.

4. The method of claim 1, wherein the signature includes a sequence of phonemes.

5. The method of claim 1, wherein the signature includes a triphone.

6. The method of claim 1, further comprising:

receiving the audible input; and

comparing the audible input to the signature.

7. The method of claim 6, wherein the audible input is received using one or more microphones.

8. A system for vocal keyword training from text, the system comprising:

a text input module configured to be stored in memory and executable by one or more processors communicatively coupled to the memory, the text input module being operable to receive the text;

a text compiler module configured to be stored in the memory and executable by the one or more processors, the text compiler module being operable to compile the text and generate a signature, the signature embodying a spoken keyword; and

a voice recognition module configured to be stored in the memory and executable by the one or more processors, the voice recognition module being operable to store the signature for comparison to an audible input.

9. The system of claim 8, wherein the text includes one or more words of pre-selected language.

10. The system of claim 8, wherein the text includes a keyword from a pre-determined list.

11. The system of claim 8, wherein the signature includes at least one of a sequence of phonemes and a triphone.

12. The system of claim 8, wherein the text input module is operable in a mobile device and one of the text compiler module and the voice recognition module is operable in a cloud-based system and the other one of the text compiler module and the voice recognition module is operable in a mobile device.

13. The system of claim 8, wherein the text input module is operable in a mobile device and both of the text compiler module and the voice recognition module are operable in a cloud-based system.

14. The system of claim 8, further comprising one or more microphones, wherein the voice recognition module is configured to:

receive, via the one or more microphones, the audible input; and

compare the audible input to the signature.

15. A computer program product comprising a non-transitory computer-readable storage having embodied thereon instructions, which when executed using one or more hardware processors, perform a method for voice keyword training from text, the method comprising:

receiving the text;

compiling the text to generate a signature, the signature embodying a spoken keyword; and

storing the signature for comparison to an audible input.

16. The computer program product of claim 15, wherein the text includes one or more words of a pre-selected language.

17. The computer program product of claim 15, wherein the text includes a keyword selected from a pre-determined list.

18. The computer program product of claim 15, wherein the signature includes at least one of a sequence of phonemes and a triphone.

19. The computer program product of claim 18, wherein the text includes one or more words of a pre-selected language, the computer program product further comprising:

receiving the audible input; and

comparing the audible input to the signature,

20. The computer program product of claim 15, further comprising:

receiving, using one or more microphones, the audible input; and

comparing the audible input to the signature.
