Abstract
A vehicle voice processor includes a processing device and a data storage medium. The processing device is programmed to receive identification information from a wearable device, identify a speaker from the identification information, identify a dialect associated with the speaker from the identification information, select a predetermined acoustic model, and adjust the predetermined acoustic model based at least in part on the dialect identified.
Claims16
A vehicle voice processor comprising a processing device and a data storage medium, wherein the processing device is programmed to:
- receive identification information from a wearable device;
- identify an individual speaker from the identification information;
- identify a dialect associated with the individual speaker;
- select a predetermined acoustic model based on the identified individual speaker;
- and
- then dynamically and in real-time adjust the predetermined acoustic model thereby generating a calibrated acoustic model, based at least in part on the dialect associated with the identified individual speaker, by reweighting feature vectors in the predetermined acoustic model in accordance with the dialect associated with the individual speaker.
A method comprising:
- receiving identification information from a wearable device;
- identifying an individual speaker from the identification information;
- identifying a dialect associated with the individual speaker;
- selecting a predetermined acoustic model;
- and
- then dynamically and in real-time adjusting the predetermined acoustic model thereby generating a calibrated acoustic model, based at least in part on the dialect associated with the identified individual speaker, by reweighting feature vectors in the predetermined acoustic model in accordance with the dialect associated with the individual speaker.
A vehicle system comprising:
- a communication device programmed to pair with the wearable device;
- a microphone configured to receive an acoustic signal;
- and
- a voice processor programmed to:
- receive identification information from the wearable device,
- identify an individual speaker from the identification information,
- identify a dialect associated with the individual speaker,
- select a predetermined acoustic model based on the identified individual speaker, and
- then dynamically and in real-time adjust the predetermined acoustic model thereby generating a calibrated acoustic model, based at least in part on the dialect associated with the identified individual speaker, by reweighting feature vectors in the predetermined acoustic model in accordance with the dialect associated with the individual speaker.
