my_hmm_gmm_speech_recognition是一个基于Python的HMM-GMM声学模型,用于语音识别。该模型利用隐马尔可夫模型(HMM)和高斯混合模型(GMM)来对语音信号进行建模和识别。HMM用于建模语音信号的时序特性,而GMM则用于对语音特征进行建模和分类。通过训练HMM-GMM模型,可以实现对语音信号的识别和理解,包括语音识别、关键词检测等...

In many modern speech recognition systems, neural networks are used to simplify the speech signal using techniques for feature transformation and dimensionality reduction before HMM recognition. Voice activity detectors (VADs) are also used to reduce an audio signal to only the portions that are ...
In this blog, I am demonstrating how to convert speech to text using Python. This can be done with the help of the “Speech Recognition” API and “PyAudio” library.

语音识别(Automatic Speech Recognition, ASR) 是一项从一段音频中提取出语言文字内容的任务。 目前该技术已经广泛应用于我们的工作和生活当中,包括生活中使用手机的语音转写,工作上使用的会议记录等等。 (出处:DLHLP 李宏毅 语音识别课程PPT) 1.2 发展历史 早期,生成模型流行阶段:GMM-HMM (上世纪90年代) 深度学习爆...
In recent years, deep learning has emerged in the field of artificial intelligence, and it has also had a profound impact on speech recognition. Deep neural networks have gradually replaced the original HMM hidden Markov model. In human communication and knowledge dissemination, about 70% of inform...
