More Information
The SpeechKit ChantSR class StartRecording method provides a simple way to pass audio files to speech recognizers. Many telephony systems process and persist audio at 8kHz. To transcribe 8kHZ audio with Dragon NaturallySpeaking, it first must be converted to a supported format.
SpeechKit 7 now automatically detects the audio format and performs the conversion before transcribing the file with Dragon NaturallySpeaking.
// Instantiate ChantSR object
NChantSR1 = new NChantSR();
// Transcribe a file of recorded audio to text
NChantSR1.StartRecording("myinaudiofile.wav");
