Claim 11:
12. A system comprising:
data processing hardware; and
memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
obtaining audio data characterizing an utterance and a corresponding ground-truth transcription of the utterance;
modifying the audio data to obfuscate a particular phrase recited in the utterance;
processing, using a trained automated speech recognition (ASR) model, the modified audio data to generate a predicted transcription of the utterance;
determining whether the predicted transcription includes the particular phrase by comparing the predicted transcription of the utterance to the ground-truth transcription of the utterance; and
when the predicted transcription includes the particular phrase, generating an output indicating that the trained ASR model leaked the particular phrase from a training data set used to train the ASR model.
