Procedure and arrangement for a language-controlled communication transmitter with acoustic operator protection against accidental tampering

摘要

The method involves providing an acoustic user menu for a communications terminal, secured against unintentional falsifications. During a reproduction of a stored speech prompt on a loudspeaker, the output signal of a microphone (1) of the communications terminal is constantly monitored through a speech recognition device (2) for an appearance of key-words which are stored for interrupting the reproduction of the speech prompt. After correct recognition of a key-word, the reproduction of the active speech prompt is interrupted at a joint position stored in the speech prompt, which is defined through a phrasing as part of a natural speech rhythm, whereby the currently active speech prompt is output always up to the next marked joint position.
