SPEECH RECOGNIZING DEVICE

摘要

PURPOSE:To provide the speech recognizing device which can securely record only a speech pattern and securely confirm the speech pattern stored as a feature pattern by reproducing the recorded speech pattern and is improved in recognition rate. CONSTITUTION:A speech section detection part 13 detects the speech section of a speech pattern supplied from a speech analytic part 12 on the basis of a low-level threshold value L and a high-level threshold value H, and generates a sound-recording request signal and a sound-recording interruption signal. A feature pattern storage part 14 stores a speech pattern corresponding to the detected speech section and a sound recording control part 16 writes the speech pattern in the speech pattern storage part 17 in response to the sound recording request signal outputted from the speech section detection part 13 and quits the writing in response to the sound-recording interruption signal.
