We are going to explore below methods of SpeechRecognition library: These APIs use different third party services to detect speech. In SpeechRecognition library, there are different methods for recognizing speech from an audio source using various APIs.

Run below command to install pyaudio python library after “portaudio” is installed successfully. If you don’t have portaudio installed, you might encounter the following error:ĮRROR: Failed building wheel for pyaudio. “portaudio” is a python independent C library, so it can’t be installed using pip. Now, before installing pyaudio for your audio input/output stream, make sure you install portaudio with the following command sudo apt-get install portaudio19-dev Install packages using following commands (if pip3 is not already installed then first install it by “sudo apt install python3-pip” command): pip3 install SpeechRecognition There are some excellent libraries available that you can use to build your speech recognition. Or if you select to use Anaconda, then you can follow the instructions at įor the below tutorial, we have used python3.x on Ubuntu 18.04. To install python, run “sudo apt install python3.7” if you are on Ubuntu or follow if you are on Windows. Either you can install Python standalone or install distribution like Anaconda which comes with Python. Now, to install Python there could be multiple ways. If you have Python already installed on your system then you can skip this step and jump on to next one. Let’s start from level 0 by installing python.

It will take little longer but you should be able to reach to the end successfully with some extra efforts.įor this tutorial, we’ll be using Python 3.x. It is good if you are little familiar with Python. Especially in personal assistant bot, dictation, voice command based control system, audio transcriptions, quick notes with audio support, voice based authentication, etc. Speech recognition could be very useful in number of applications. Many of the things you will find pre-built and you can build your functionality on top of it.įor speech recognition too, Python has many libraries to make your development process easy and faster.Īnd one more thing, if you are familiar with C/C++ or PHP or any other basic language then learning Python becomes pretty easy. Python has rich libraries to offer which will make your life fairly easier while developing complex applications. If you are looking to get started with building Speech Recognition / Audio Transcribe in Python then this small tutorial could be very helpful and will provide basic insights to get started. It is also known as Speech to Text (STT).

In Speech Recognition, spoken words/sentences are translated into text by computer. Speech Recognition is a part of Natural Language Processing which is a subfield of Artificial Intelligence.
