如何将人声转换为数字格式? [英] How to convert human voice into digital format?

问题描述

我正在一个使用生物识别系统保护系统安全的项目中.我们计划使用人的声音来保护系统.

I am working on a project where biometric system is used to secure the system. We are planning to use human voice to secure the system.

想法是允许该人说一些单词或句子，并且系统将以数字格式存储该语音.下次用户想进入系统时，他/她必须说一些可能与以前使用的词不同的词.

Idea is to allow the person to say some words or sentences and system will store that voice in digital format. Next time person wants to enter the system, he/she has to speak some words which may or may not be different from the words used earlier.

我们不想匹配单词，但希望匹配语音频率.

We don't want to match words but want to match voice frequency.

我已经阅读了一些有关此系统的研究论文，但是这些论文没有任何实现细节.

I have read some research papers regarding this system but those papers don't have any implementation details.

所以只想知道是否有任何软件/API可以将模拟语音转换为数字格式，并且还会告诉我们语音的频率.

So just want to know whether there is any software/API which can convert analog voice into digital format and will also tell us the frequency of voice.

直到现在我仍在研究基于Web的普通应用程序，因此我了解Java EE，C#等常规API和平台，但对此类应用程序没有任何经验.

Until now I was working on normal web based applications so I know normal APIs and platforms like Java EE, C#, etc but I don't have any experience about this kind of application.

请赐教！！！
