VoicePrint

1. 程序说明

VoicePrint (算法原理说明点我) 是一款基于高斯混合模型的文本无关的声纹识别算法验证程序

VoicePrint的特点是:

  • 语音特征向量:采用 MFCC系数(梅尔倒谱系数)
  • 模式匹配模型:采用 GMM 模型(高斯混合模型)

2. 最近更新

VoicePrint V1.1正式版

  • 修复建模、识别过程中间语音转储临时文件可能无法删除。
  • 修改语音段数由 3 改为 4,每段语音改为定长的 50 帧。
  • GMM模型数据转储文件结构微调,不再兼容 V1.1 以前的版本。

VoicePrint V1.0

  • 增加了将 GMM 模型数据导出为文件的功能,并能把文件导入程序。
  • 修改了识别范围值。
  • 修改了声纹识别算法,改为动态数组分配内存。

3. 温馨提醒

本程序为课程实验验证开发,所实现的声纹识别算法难免有错误及不妥之处!

提醒:因为本程序是简略的验证程序,建议不要在正式项目中直接使用本程序中的声纹识别代码。

TODO:

  • 音量归一化(暂无,提高识别率)
  • 去除背景噪声(暂无,提高识别率)
  • iOS Demo(2016年)
  • 英文注释及 README(2016年)
