offline speech recognition data

Wen/Zhang Junbo Know the link: https://www.zhihu.com/question/20398418/answer/18080841 Briefly introduce you to the voice of how to change the text. Hope this introduction can let all students understand. First, we know that sound is actually a wave. Common MP3, WMV and other formats are compressed format, must be converted into a uncompressed pure waveform file to deal with, such as Windows PCM files, commonly known as WAV files. WAV files stored in addition to a file header, is the sound wav

Today from the Internet to find an example of the realization of speech recognition, personal feeling quite fun, put the code posted to share with you under: Android mainly through the recognizerintent to achieve speech recognition, in fact, the code is relatively simple, but if the settings can not be found, will thr

Using intent to invoke speech recognition programs Description Android mainly through recognizerintent to achieve speech recognition, in fact, the code is relatively simple, but if the speech recognition device can not be found,

The Kinect microphone array is below the Kinect device. This column consists of 4 independent microphones horizontally distributed below the Kinect. Although each microphone captures the same audio signal, the array can detect the source direction of the sound. So that it can be used to identify the sound coming from a particular direction. The audio data stream captured by the microphone array is processed by a complex audio enhancement algorithm to

range and precision and to prevent the transition beyond the dynamic limit. The non-optimal range of regular fixed-point operands may cause the operand to wrap around (wrap around, such as (max+1) (min)) and cause severe clipping and error. The precision of the fixed-point is equally important, especially in the repetitive signal processing operations. When the accuracy is not enough, repetitive signal processing algorithm will lead to fault propagation and error accumulation, the final signal

large vocabulary speech recognition on the mobile terminal at this stage. It may be possible to wait until our phone has several T storage spaces. By then, the whole field of AI might have had a huge impact on our lives.But this does not mean that CMU Sphinx has no practical use. The application described above is full vocabulary recognition, but there are occas

also needs to distinguish the legato and the tone of the continuous speech input, and it requires the more reasonable result according to the context and the hot word output. The less restrictive the condition, the greater the difficulty of speech recognition. Because to some extent avoid fuzzy sound, the less the dictionary

This paper mainly introduces the traditional speech recognition system based on Gmm/hmms. Outline: Recognition Principle Statistics Model system framework First, it is necessary to explain that the object discussed in this article is Continuous speech recognition (continuous

Android mainly through recognizerintent to achieve speech recognition, in fact, the code is relatively simple, but if you cannot find the settings, will throw an exception activitynotfoundexceptioN, so we need to catch this exception. and speech recognition is not tested on the simulator, because

Apple's iphone has Google's technology for voice recognition, and Android, Google's push, will naturally implant its core technology into Android and build it up with Google's cloud technology. So Google Voice recognition's implementation on Android became extremely easy. Speech recognition, with the help of cloud technology to identify the user's voice input,

Today, I found an example on the Internet to implement speech recognition. I personally think it is quite interesting.CodePost it to share with you: Android uses recognizerintent to implement speech recognition. In fact, the code is relatively simple. However, if the setting cannot be found, an exception activitynotf

Android Speech Recognition ---> RecongnizerIntent implementation, First, let's talk about the betting points: Android uses RecognizerIntent to implement speech recognition. In fact, the code is relatively simple. However, if the setting cannot be found, an exception ActivityNotFoundException will be thrown, so we need

buffer area is recycled to improve the real-time performance of the system; When data in a cache area is filled up, the system extracts data from the buffer zone and analyzes the data. First, the system adds a window to the digital voice signal and splits the frame, the length of each frame is 20 ms, and the frame is moved to 10 ms. Each frame includes 160 sampl
