Voice Assistant Error Detection System
30 Mar 23
A vehicle system for classifying spoken utterance within a vehicle cabin as one of system-directed and non-system directed, the system may include at least one microphone configured to detect at least one acoustic utterance from at least one occupant of a vehicle, at least one sensor to detect user behavior data indicative of user behavior, and a processor programmed to: receive the acoustic utterance, classify the acoustic utterance as one of a system-directed utterance and a non-system directed utterance, determine whether the acoustic utterance was properly classified based on user behavior observed via data received from the sensor after the classification, and apply a mitigating adjustment to classifications of subsequent acoustic utterances based on an improper classification.

Techniques for Language Independent Wake-up Word Detection
16 Mar 23
A method for a user device, including receiving a first acoustic input of a user speaking a wake-up word in the target language; providing a first acoustic feature derived from the first acoustic input to an acoustic model stored on the user device to obtain a first sequence of speech units corresponding to the wake-up word spoken by the user in the target language, the acoustic model trained on a corpus of training data in a source language different than the target language; receiving a second acoustic input including the wake-up word in the target language; providing a second acoustic feature derived from the second acoustic input to the acoustic model to obtain a second sequence of speech units corresponding to the wake-up word in the target language; and comparing the first and second sequences of speech units to recognize the wake-up word in the target language.
