1. A computer based method in a vehicle comprising the steps of:
- receiving a representation of first voice input;
determining a first characteristic of the first voice input representation wherein the first characteristic is at least one of a voice type, frequency, speed, prosody, intelligibility, tone, pitch, size, direction, volume and/or duration;
based on the determined first characteristic, determining whether a voice recognition process should be performed to said first voice input representation by a computer based voice recognition system in the vehicle or using a voice recognition system that is external to the vehicle;
performing said computer based voice recognition in the vehicle to said first voice input representation in response to said determination that the voice recognition process should be performed in the vehicle; and
transmitting said first voice input representation to an external system in response to said determination that the voice recognition process should be performed external to the vehicle; and
further comprising the steps of;
determining if a wireless transmission connection between the vehicle and the external system exceeds a minimum threshold when the determination is to use the external voice recognition system; and
determining that said voice recognition process should be performed using the voice recognition system in the vehicle to said representation of said first voice input representation if said wireless transmission connection quality is lower than said minimum threshold.

1. A computer based method in a vehicle comprising the steps of:
-
receiving a representation of first voice input; determining a first characteristic of the first voice input representation wherein the first characteristic is at least one of a voice type, frequency, speed, prosody, intelligibility, tone, pitch, size, direction, volume and/or duration; based on the determined first characteristic, determining whether a voice recognition process should be performed to said first voice input representation by a computer based voice recognition system in the vehicle or using a voice recognition system that is external to the vehicle; performing said computer based voice recognition in the vehicle to said first voice input representation in response to said determination that the voice recognition process should be performed in the vehicle; and transmitting said first voice input representation to an external system in response to said determination that the voice recognition process should be performed external to the vehicle; and
further comprising the steps of;
determining if a wireless transmission connection between the vehicle and the external system exceeds a minimum threshold when the determination is to use the external voice recognition system; and
determining that said voice recognition process should be performed using the voice recognition system in the vehicle to said representation of said first voice input representation if said wireless transmission connection quality is lower than said minimum threshold. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A system in a vehicle comprising:
-
a microphone for receiving a first voice input representation from a first user; a voice recognition location unit for; determining a first characteristic of said first voice input representation wherein said first characteristic is at least one of a voice type, frequency, speed, prosody, intelligibility, tone, pitch, size, direction, volume and/or duration; based on the determined first characteristic, determining whether a voice recognition process should be performed to said first voice input representation by a computer based voice recognition system in the vehicle or using a voice recognition system that is external to the vehicle;
said voice recognition system for performing said computer based voice recognition in the vehicle to said first voice input representation in response to said determination that the voice recognition process should be performed in the vehicle; and
a communications unit for transmitting said first voice input representation to an external system in response to said determination that the voice recognition process should be performed external to the vehicle;
wherein said communications unit determines if a wireless transmission connection between the vehicle and the external system exceeds a minimum threshold when the determination is to use the external voice recognition system; and
wherein said voice recognition location unit further determines that said voice recognition process to said first voice input representation should be performed using the voice recognition system in the vehicle if said wireless transmission connection quality is lower than said minimum threshold. - View Dependent Claims (10, 11, 12)

13. One or more non-transitory computer-readable storage mediums having computer-executable instructions, the instructions when executed cause at least one processor to perform steps including:
-
receiving a first voice input representation from a first user of the vehicle; determining a first characteristic of said first voice input representation wherein said first characteristic is at least one of a voice type, frequency, speed, prosody, intelligibility, tone, pitch, size, direction, volume and/or duration; determining whether a voice recognition process should be performed to said first voice input representation by a computer based voice recognition system in the vehicle or by a voice recognition system that is external to the vehicle based on the determined first characteristic; performing said computer based voice recognition to said first voice input representation in the vehicle in response to said determination that the voice recognition process should be performed in the vehicle; and
transmitting said first voice input representation to an external system in response to said determination that the voice recognition process should be performed external to the vehicle; and
further comprising the steps of;
determining if a wireless transmission connection between the vehicle and the external system exceeds a minimum threshold when the determination is to use the external voice recognition system; and
determining that said voice recognition process should be performed using the voice recognition system in the vehicle if said wireless transmission connection quality is lower than said minimum threshold. - View Dependent Claims (14, 15, 16)
