Method for operating a speech recognition system

摘要

A method for operating a speech recognition system is described in which a speech signal (S1) of a user is detected and analyzed so as to recognize speech information contained in the speech signal (S1). The speech recognition system determines a reception quality value (SQ) or a noise value which represents a current reception quality. The speech recognition system is switched over to a mode of operation which is less sensitive to noise and/or outputs an alert signal (SW) to the user when the reception quality value (SQ) drops below a given reception quality threshold or when the noise value exceeds a noise threshold. An appropriate speech recognition system is also described.

1. A method for operating a speech recognition system comprising acts of:
detecting a speech signal of a user; analyzing the speech signal to recognize speech information contained in the speech signal; determining a reception quality value or a noise value which represents a current reception quality; and switching the speech recognition system over to a mode of operation which is less sensitive to noise in response to determining that the noise value has exceeded a noise threshold or that the reception quality value has dropped below a reception quality threshold, or both; and automatically resetting the speech recognition system to a previous mode of operation in response to determining that the reception quality value has exceeded the reception quality threshold or that the noise value has dropped below the noise threshold.
