Hello everyone, I am a ruffian balance, is a serious technical ruffian. Today, ruffian Heng is to introduce to you the speech processing tool pzh-py-Speech birth environment.
To write Pzh-py-Speech, you need to set up the development environment first. The following table lists all the software/toolkits that will be used during development:

Python + PyAudio + Matplotlib + NumPy
The pzh-py-Speech tool is a fully developed application based on Python language. Install Python 2.7.14, and install C: tools_mcu\Python27. Make sure to include the path (C:\tools_mcu\Python27) in the system environment variables after the installation is complete, as this path contains python.exe, which will be called by subsequent Python commands. PIP is a Python package management tool that allows you to install PyAudio and Matplotlib packages (NumPy is included in Matplotlib) :
PS C:\tools_mcu\Python27\Scripts> .\pip.exe install pyaudio

With PyAudio you can read and write Audio, and with Matplotlib you can graphically display Audio as a waveform. With these two tools installed, the Python infrastructure for JaysPySPEECH tool development is ready.
Note: For the installation of GUI and debugging tools (wxPython, wxFormBuilder, PyCharm), please refer to tinyPyCOM, another work of Ruffian.
SpeechRecognition + PocketSphinx + PyTTSX3 + eSpeak
Pzh-py-speech was originally designed to support speech recognition and text-to-speech conversion, as we needed to install Python libraries. SpeechRecognition is a popular Python library that supports multiple engines for speech recognition. It’s your choice for Pzh-py-Speech. The voice recognition engine is PocketSphinx, which can work offline. The installation is as follows:
PS C:\tools_mcu\Python27\Scripts> .\pip.exe install SpeechRecognition

Pyttsx3 is a lightweight Python library, which is a continuation of the classic pyTTS and PyTTSX projects. Its core is Microsoft Speech API (SAPI5), which can work offline. Specific installation is as follows:

Pyttsx3 can only speak online and cannot be saved to WAV files, so we need a TTS that can save WAV files. At this point, the Python environment for pzh-py-Speech tool development is complete.
With that, the environment for the birth of pzh-py-Speech is over, where is the applause ~~~
