Certain aspects disclosed herein improve on inappropriate behavior detection by applying machine-learning techniques to identify inappropriate behavior in real-time, or near real-time. For example, one or more patterns can be generated that represent possible incidences of inappropriate behavior, such as a request for a user's contact information. Audio segments captured by a wireless device in a vehicle can be converted into text using an automatic speech recognition system, and an adaptation model can apply the pattern(s) to the text to determine portions of the text that match at least one pattern and portions of the text that do not match any pattern, with the adaptation model labeling the text portions accordingly. The adaptation model can then pre-train a text classification model with the labeled text portions. The adaptation model obtains manually labeled data points and re-trains or updates the pre-trained text classification model using the manually labeled data points.
A computer-implemented method for detecting a request for contact information in a vehicle, the computer-implemented method comprising:
A system comprising:
Non-transitory, computer-readable storage media comprising computer executable instructions for detecting a request for contact information in a vehicle, wherein the computer-executable instructions, when executed by a computing system, cause the computing system to:
