Microphone and communication interface system

Abstract

It is possible to improve a defect of an analysis object itself of a mobile telephone and speech recognition which is an air propagating normal speech taken from outside by a microphone and realize a new mobile terminal communication based on the human cultural habit in the personal mobile information terminal without requiring training. A stethoscope type microphone is mounted on a human skin surface so as to take a meat-propagating vibration sound of un-hearable murmur articulated by a speech act (mouth movement) without using vocal cord regular vibration. The meat-propagating vibration sound of the amplified non-hearable murmur is like a whisper and the whisper itself can be heard and understood by a human. Accordingly, it can be used for communication via a mobile telephone. Moreover, by making the meat-propagating vibration sound of the un-hearable murmur an object of analysis / parameterization, it is possible to realize a kind of soundless recognition as a new input method of a personal mobile information terminal.

Description

technical field [0001] The present invention relates to a microphone and communication interface system. In particular, the present invention relates to a method for detecting vibrations involving non-audible breath sounds transmitted through internal soft tissues (hereinafter referred to as "body conduction"). sound (hereinafter referred to as "non-audible murmur (non-audible murmur)" for short), and a communication interface system using the microphone, wherein the breath sound is generated by a resonant filter associated with the movement of the vocal organ The breath sound does not contain regular vocal cord vibrations. In addition, the breath sound does not refer to the sound heard by the surrounding people, but contains a small breathing flow rate (expiratory flow rate and inspiratory flow rate). Background technique [0002] The rapid proliferation of cellular phones has created problems for the way conversations are carried on public transport such as trains or buses...

AI Technical Summary

Problems solved by technology

[0009] In contrast, the problem with using speech recognition technology in a silent environment is that the sound is the same as noise to those around you

However, the technology disclosed in this publication does not clearly show that body vibrations can be used as input for speech recognition devices or for conversations via cell phones

Furthermore, this technique does not clearly show that the inaudible murmur produced without the regular vibrating vocal cords can be used as input for speech recognition devices, or for conversation via cell phone
