Radiotelephone system, particularly for motor vehicles
First Claim
1. A speech recognition system for an automatic voice controlled radiotelephone system having a radiotelephone, comprising:
- transducer means for remote pickup, processing and transmitting of speech of a user;
recognizing means for recognizing a user control vocabulary including numbers and key words associated with stored telephone numbers, said control vocabulary stored in a directory and derived from speech of a user of the speech recognition system;
a central processing unit connected to said recognizing means and including plural memories for controlling automatic dialing of telephone numbers on the radiotelephone in response to a recognition by said recognizing means of numbers and key words stored in said directory;
synthesis means for synthesizing of set speech signals suitable for generating, under the control of the central processing unit, permanently stored messages;
recording means including a scratchpad for recording of non-permanent voice messages from the transducer means or from the radiotelephone and for playback of the recorded messages;
selecting means for selecting predetermined modes of operation of said speech recognition system; and
interface means controlled by said central processing unit for controlling connections between said central processing unit, said means for synthesis, said transducer means, said recording means, and said recognizing means;
wherein said predetermined modes selected by said selecting means comprise;
a normal operation mode in which said recognizing means and said synthesis means are inhibited and a telephone communication between the user and another party is established upon said user receiving a call from said another party, anda standby operation mode in which upon receiving a call from said another party, said another party can retrieve non-permanent voice messages stored in said scratchpad; and
means for detecting a confidential code sent by said another party to enable addressing of said scratchpad and retrieving by said another party of said non-permanent voice messages stored in said scratchpad only upon detection of said confidential code.
