Abstract

Systems and methods for training voice activation control of electronic equipment are disclosed. One example method includes receiving a selection corresponding to at least one command used to control the electronic equipment. The method further includes instructing a user to speak, and responsive to the instruction, receiving a digitized speech stream. The method further includes segmenting the speech stream into speech segments, storing at least one of the speech segments as an entry in a dictionary, and associating the dictionary entry with the selected command.

Claims

1. A method for training voice activation control of a television program processing device (TPPD), comprising:

receiving a first input from a user corresponding to a request for a training procedure;

responsive to receiving the first input, muting audio of a tuned television program in the TPPD;

receiving a digitized audio signal (DAS) at a receiver of the TPPD after muting the audio of the tuned television program at the TPPD;

processing the DAS received at the TPPD;

storing the processed DAS (PDAS) in the TPPD; and

associating the stored PDAS with functionality of the TPPD that corresponds to television navigation.

2. The method of claim 1, wherein the first input is received while the TPPD is tuned to the television program.

3. The method of claim 1,

wherein the DAS received at the TPPD includes compressed data.

4. The method of claim 3, wherein processing of the DAS received at the TPPD includes decompressing the compressed data included in the received DAS.

5. The method of claim 4, wherein the DAS received at the TPPD includes one or more spoken words provided by the user, and wherein at least a portion of the decompressed data in the TPPD corresponds to the one or more spoken words provided by the user.

6. The method of claim 1, further comprising responsive to receiving the first input, providing to the user information to enable microphone functionality.

7. The method of claim 6, further comprising responsive to providing the user information to enable the microphone functionality, enabling the microphone functionality in a television remote control device (TRCD).

8. The method of claim 7, further comprising receiving from the user a second user input corresponding to a selection of a television navigation command (TNC), and associating the user-selected TNC with the stored PDAS in the TPPD, wherein at least a portion of the DAS received at the TPPD includes one or more spoken words provided by the user.

9. The method of claim 8, wherein the one or more spoken words provided by the user included in the DAS received at the TPPD are provided while the audio of the tuned television program in the TPPD is muted.

10. The method of claim 7, further comprising receiving one or more spoken words provided by the user after enabling the microphone functionality in the TRCD, and processing the one or more spoken words provided by the user in the TRCD, wherein the DAS received at the TPPD is emitted by the TRCD, and wherein the DAS received at the TPPD includes the one or more spoken words provided by the user.

11. The method of claim 1, wherein the DAS received at the TPPD includes a start command.

12. The method of claim 11, wherein the DAS received at the TPPD further includes, after the start command, one or more spoken words provided by the user.
