Abstract

According to an embodiment of the disclosure, there is provided a method of choosing a nametag using automatic speech recognition (ASR). The method includes receiving a spoken nametag via a microphone; performing a first speech recognition analysis on the spoken nametag; determining that the first speech recognition analysis outputs only handheld wireless device nametags; performing a second speech recognition analysis that excludes the handheld wireless device nametags stored at the handheld wireless device; and combining the results of the first speech recognition analysis and the second speech recognition analysis.

Claims

1. A method of choosing a nametag using automatic speech recognition (ASR), comprising the steps of:

(a) receiving a spoken nametag via a microphone;

(b) performing a first speech recognition analysis on the spoken nametag;

(c) determining that the first speech recognition analysis outputs only handheld wireless device nametags;

(d) performing a second speech recognition analysis that excludes the handheld wireless device nametags stored at a handheld wireless device; and

(e) combining the results of the first speech recognition analysis and the second speech recognition analysis.

2. The method of claim 1, further comprising the step of performing the second speech recognition on vehicle telematics nametags.

3. The method of claim 1, further comprising the step of determining whether any vehicle telematics nametags are stored at a vehicle before performing the second speech recognition analysis.

4. The method of claim 1, wherein the spoken nametag includes a vehicle telematics nametag.

5. The method of claim 1, further comprising the step of performing the first speech recognition analysis by searching for a vehicle telematics nametag in a memory device located in the vehicle telematics unit and the handheld wireless device nametag in a phonebook at a handheld wireless device.

6. The method of claim 1, further comprising the step of initiating an ASR system with a button push before receiving the spoken nametag via the microphone.

7. The method of claim 1, wherein the handheld wireless device nametags are accessed using a Bluetooth phonebook access profile (PBAP).

8. A system for choosing a nametag using automatic speech recognition (ASR), comprising:

a vehicle telematics unit that includes a processor, a computer-readable memory device storing data and speech recognition software, and a short-range wireless antenna that are each installed on a vehicle, wherein the vehicle telematics unit establishes a wireless link with a handheld wireless device using the short-range wireless antenna, accesses one or more handheld wireless device nametags stored at the handheld wireless device via the wireless link, searches the computer-readable memory for vehicle telematics nametags, and if found, performs speech recognition on the vehicle telematics nametag entries found in the computer-readable memory while excluding the handheld wireless device nametags accessed through the wireless link.
