Abstract:
An exemplary computer system configured to train an ASR using the output from a TTS engine.

Claim (Index 1):
An automatic speech recognition (ASR) system comprising:\n a first speech input module configured to receive a speech corpus comprising first prosody information of at least one speech audio file of a first speaker and first phonetic transcriptions corresponding to the at least one speech audio file; a first text-to-speech (TTS) engine configured to receive the first prosody information and the first phonetic transcriptions from the first speech input module, synthesize at least one speech audio file of the first speaker into a first audio waveform having a first prosody based on the first prosody information, and output the first audio waveform; a speech morphing module configured to morph human speech of a second speaker having a second prosody into morphed human speech of the first speaker having a prosody that is the same as first prosody of the first audio waveform of the at least one speech audio file of the first speaker output by the first TTS engine, the speech morphing module comprising:\n a second TTS engine configured to receive a speech corpus comprising second prosody information of at least one speech audio file of the human speech of the second speaker and second phonetic transcriptions corresponding to at least one speech audio file of the human speech of the second speaker, and output a second audio waveform of speech of the second speaker having a second prosody based on the second prosody information; \n a first neural network configured to receive the first audio waveform and the second audio waveform, and create a mathematical model of the first audio waveform and the second audio waveform; and \n a second neural network configured to receive the mathematical model and the second audio waveform, and output the morphed human speech; and \n an ASR engine comprising an acoustic model, the ASR engine configured to convert speech into text, wherein the ASR engine is configured to receive the first audio waveform and the phonetic transcriptions output by the first TTS engine, receive the morphed human speech morphed by the speech morphing module, create the acoustic model through training on the first audio waveform and the first phonetic transcriptions output by the first TTS engine by compiling the first audio waveform and the first phonetic transcriptions output by the first TTS engine into statistical representations of words of the audio waveform based on the phonetic transcriptions, recognize the morphed human speech based on the trained acoustic model, and output text corresponding to the recognized morphed human speech.
