Adaptive speech recognition methods and systems

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, when executed by a processing system, cause the processing system to:

• analyze a transcription of an audio communication with respect to a vehicle to characterize a nonstandard pattern within the transcription of the audio communication;
• obtain a ground truth for the transcription of the audio communication;
• determine one or more performance metrics associated with the nonstandard pattern within the transcription based on a relationship between the transcription of the audio communication and the ground truth for the transcription;
• update a speech recognition vocabulary to include the nonstandard pattern based at least in part on the one or more performance metrics, resulting in an updated speech recognition vocabulary;
• and
• determine an updated speech recognition model for the vehicle using the updated speech recognition vocabulary and the audio communication.

A computing device comprising:

• at least one computer-readable storage medium to store computer-executable instructions;
• and
• at least one processor, coupled to the at least one computer-readable storage medium, to execute the computer-executable instructions to:
• analyze a transcription of an audio communication with respect to a vehicle to characterize a nonstandard pattern within the transcription of the audio communication;
• obtain a ground truth for the transcription of the audio communication;
• determine one or more performance metrics associated with the nonstandard pattern within the transcription based on a relationship between the transcription of the audio communication and the ground truth for the transcription;
• update a speech recognition vocabulary to include the nonstandard pattern based at least in part on the one or more performance metrics, resulting in an updated speech recognition vocabulary;
• and
• determine an updated speech recognition model for the vehicle using the updated speech recognition vocabulary and the audio communication.
