  • Speech verification
    Speech verification
    Speech verification uses speech recognition to verify the correctness of the pronounced speech. Speech verification doesn't try to decode unknown speech from a huge search space, but instead, knowing the expected speech to be pronounced, it attempts to verify the correctness of the utterance's...
