UA51137U - Digital dictophone voice activation method - Google Patents

Abstract

A digital dictophone voice activation method relates to the field of speech signal recognition and is meant for creation of a portable voice activation digital dictophone.

Description

The functions of the recorder are controlled by 4 digital signal processing processors; using voice commands. For this, use 5 - non-volatile memory; the user must name the command and/or file name. Re-6 - digital-analog converter; the result of the command, a hint or detected errors - 7 - record/power buttons; which are announced in the form of voice messages. 8 - voice command input buttons;

File naming is done by the user during 9 - two light indicators; or after recording. For this user- 10 - speaker or audio output of the main stream, it is enough to say the name of the file. By this name the Lephons; the file is stored in the file system, and all other accesses to the file take place under the same 11 - output for connecting the recorder to the computer. thermistor (5V port);

For example, playing a file looks like this: co- 12 - battery. the user utters the command "READ" and the name Microphones 1 is attached to the analog file. To delete a file, the user speaks digital converter 2, while one says "DELETE FILE", the voice recorder asks for the name of the file, the microphones are activated in recording mode, and the other one is silent, the user says the name. Erasing requires voice recognition mode. Analog - confirmation, so the recorder asks: "Are you really connecting the digital converter 2 to the process - do you want to erase this file?". If the user responds positively to the processor, i.e. "YES", the file is deleted - digital signal processing 4 attaches the microcon, otherwise it is not deleted. Another example, troller 3 and digital-to-analog converter 6, after speaking the commands "READ", "FOR- which has an output to the speaker or headphones

Microcontroller 3, in addition to the processor, is connected by voice "Say the name of the file to read", "Na- with the keyboard 7, 8, light indicators 9 and report the name of the file for recording" or informs: "File in external memory 5.

The second button is intended for entering early messages by sound. voice command. The light indicators show
