Abstract

An electronic device is configured to receive data from a keypad key, wherein the key is associated with first and second alphanumeric characters. The device includes a keypad interface and a data entry processor. The keypad interface is configured to determine the first and second alphanumeric characters when the key is pressed. The data entry processor is configured to select the first alphanumeric character from among the first and second alphanumeric characters when a speech recognizer determines that a spoken entry identifies the first alphanumeric character.

Claims

1. An electronic device configured to receive data from a keypad key, said key being associated with first and second alphanumeric characters, and comprising:

a keypad interface configured to determine said first and second alphanumeric characters when said key is pressed;

a data entry processor configured to select said first alphanumeric character from among said first and second alphanumeric characters when a speech recognizer determines that a spoken entry identifies said first alphanumeric character.

2. The device of claim 1, wherein said keypad is a telephone keypad.

3. The device of claim 1, wherein said keypad is a full keyboard.

4. The device of claim 3, wherein said key is a first key, said alphanumeric character is assigned to said first key, and said second alphanumeric character is assigned to a key immediately neighboring said first key.

5. The device of claim 1, wherein said speech recognizer constrains possible alphanumeric character matches to only alphanumeric characters associated with said pressed key.

6. The device of claim 1, further comprising said speech recognizer.

7. The device of claim 1, wherein said speech recognizer is provided by a remote server in communication with said electronic device.

8. The device of claim 7, wherein said device and said remote server communicate via a cellular communication link.

9. The device of claim 1, wherein said first and second alphanumeric characters are both assigned to said keypad key.

10. The device of claim 1, wherein said speech recognizer is configured to parse said spoken entry into a spoken character and a modifier keyword, and to modify said spoken character in accordance with said modifier keyword.

11. A system for entering data into an electronic device, comprising:

a receiver configured to receive keypad entry data from said electronic device;

a data discriminator configured to determine a pressed key from among at least a first key and a second key of said keypad;

a speech recognizer configured to receive a spoken entry that corresponds to a first or a second alphanumeric character associated with said pressed key; and

a character transmitter configured to transmit to said electronic device a signal indicating which of said first and second alphanumeric characters is designated by said spoken entry.

12. The system of claim 11, further comprising a cellular telephone configured to transmit said keypad entry data.

13. The system of claim 11, wherein said first and second alphanumeric characters are assigned to said key.

14. The system of claim 11, wherein said first and second alphanumeric characters are neighboring characters on said keypad.

15. The system of claim 11, wherein said speech recognizer is configured to constrain possible alphanumeric character matches to only alphanumeric characters associated with said pressed key.

16. A method of forming a keypad-operated electronic device, comprising:

providing a keypad interface configured to determine that a keypad key has been pressed;

configuring a speech recognizer to process a spoken entry including a spoken equivalent of a first alphanumeric character associated with said key;

coupling to said speech recognizer a data entry processor configured to select said first alphanumeric character from among a plurality of alphanumeric characters associated with said key when said speech recognizer determines that said spoken entry identifies the first alphanumeric character.

17. The method of claim 16, further comprising configuring said speech recognizer to constrain possible alphanumeric character matches to only alphanumeric characters associated with said pressed key.

18. The method of claim 16, wherein said keypad is a telephone keypad.

19. The method of claim 16, wherein said speech recognizer is collocated with a server remote from said electronic device.

20. The method of claim 19, wherein said electronic device and said server are configured to communicate via a cellular communication link.
