Abstract

A computer-implemented method for hybrid speech data processing in a vehicle includes receiving a first speech input at an input device in the vehicle and digitizing the first speech input into packets. The method includes storing the packets at a memory for predetermined amount of time and transmitting the packets using a wireless voice communication channel to a speech recognition server. Upon detecting a speech recognition condition is met associated with the packets or the wireless voice communication channel, the method includes converting one or more of the packets stored at the memory into text data and transmitting the text data using a wireless data communication channel to an interactive voice response system. Further, the method includes receiving a speech recognition result from the interactive voice response system and outputting the speech recognition result in the vehicle using an output device.

Claims

1. A computer-implemented method for hybrid speech data processing in a vehicle, comprising:

receiving a first speech input at an input device in the vehicle;

digitizing the first speech input into packets;

storing the packets at a memory for predetermined amount of time;

transmitting the packets using a wireless voice communication channel to a speech recognition server;

upon detecting a speech recognition condition is met associated with the packets or the wireless voice communication channel, converting one or more of the packets stored at the memory into text data;

transmitting the text data using a wireless data communication channel to an interactive voice response system;

receiving a speech recognition result from the interactive voice response system; and

outputting the speech recognition result in the vehicle using an output device.

2. The computer-implemented method of claim 1, wherein converting the one or more of the packets includes converting the one or more of the packets of the first speech input received by the input device after detecting the speech recognition condition.

3. The computer-implemented method of claim 1, wherein converting the one or more of the packets includes converting the one or more of the packets of the first speech input received by the input device prior to detecting the speech recognition condition and received by the input device after detecting the speech recognition condition.

4. The computer-implemented method of claim 1, wherein the wireless voice communication channel and the wireless data communication channel are established using cellular communication network.

5. The computer-implemented method of claim 1, wherein the wireless data communication channel is established using non-cellular wireless communication.

6. The computer-implemented method of claim 1, wherein the interactive voice response system converts the text data to speech data and transmits the speech data to a third party for speech recognition processing.

7. The computer-implemented method of claim 1, wherein the speech recognition condition is based on cellular plan usage, the cellular plan associated with the vehicle.

8. A system for hybrid speech data processing in a vehicle, comprising:

a vehicle computing device including an input device, an output device, and a communication interface, each of which are operably connected for computer communication to the vehicle, wherein the input device receives a first speech input in the vehicle and the vehicle computing device digitizes the first speech input into packets; and

a network interface controller of the communication interface, where the network interface controller transmits the packets using a first communication channel established using a cellular communication network to a server for speech recognition processing,

wherein the server is operably connected for computer communication to the vehicle computing device, the network interface controller detects a speech recognition condition associated with the packets or the first communication channel and the communication interface converts a portion of the packets into text data,

wherein the network interface controller transmits the text data using a second communication channel established using the cellular communication network to the server for speech recognition processing and receives a speech recognition result from the server,

wherein the output device outputs the speech recognition result in the vehicle.

9. The system of claim 8, including a memory operably connected for computer communication to the vehicle, wherein the communication interface stores the packets into the memory for a predetermined period of time.

10. The system of claim 9, wherein the portion of the packets includes one or more of the packets of the first speech input received by the input device prior to detecting the speech recognition condition and received by the input device after detecting the speech recognition condition.

11. The system of claim 8, wherein he network interface controller transmits the text data using the second communication channel established using the cellular communication network to an interactive voice response system.

12. The system of claim 11, wherein the interactive voice response system converts the text data into speech data and transmits the speech data to a third party for speech recognition processing.

13. The system of claim 8, wherein the first communication channel is a voice channel and the second communication channel is a data channel.

14. The system of claim 8, wherein the speech recognition result from the server is based on a context from the text data and previously analyzed speech recognition results.

15. A non-transitory computer readable medium with instructions for hybrid speech data processing in a vehicle, the instructions for execution by a processor, comprising:

receiving a first speech input at an input device in the vehicle;

digitizing the first speech input into packets;

storing the packets at a memory for a predetermined amount of time;

transmitting the packets using a wireless voice communication channel to a speech recognition server;

detecting a speech recognition condition is met associated with the packets or the wireless voice communication channel and converting one or more of the packets into text data;

transmitting the text data using a wireless data communication channel to an interactive voice response system;
