Introduction to pyttsx3 python library

  • Text-to-speech is a type of speech synthesis application that is used to create a spoken sound version of the text in a computer document, such as a help file or a Web page.
  • Text-to-speech is commonly used as an accessibility feature to help people who have trouble reading on-screen text may be due to more brightness.
  • There are several APIs available to convert text to speech in python. One of them is the Python Text to Speech API commonly known as the pyttsx3 API.
  • It a very easy to use tool which converts the text entered, into audio.

What is pyttsx3 library?

pyttsx3 is a text-to-speech conversion library in Python. It is a cross-platform text to speech library which is platform independent. The major advantage of using this library for text-to-speech conversion is that it works offline.

Why pyttsx3?

  • Other text-to-speech APIs may work only in online mode but pyttsx3 library works in offline mode also.
  • Without saving the text as audio file, pyttsx speaks it there which makes it more reliable to use for voice-based projects.
  • pyttsx3 supports two voices first is female and the second is male which is provided by “sapi5” for windows.
  • We can change the voice, volume and set the rate of the voice.

Installation

To install the pyttsx3 API, open terminal and write:

$ pip install pyttsx3

We may get an error while executing the program as it is dependent on win32. To avoid this error simply install pypiwin32 in your environment-

$ pip install pypiwin32

Lets get started!!!

Listed are the functions:

  • pyttsx3.init([driverName : string, debug : bool]) – Gets a reference to an engine instance that will use the given driver. If the requested driver is already in use by another engine instance, that engine is returned. Otherwise, a new engine is created.
  • getProperty(name : string) – Gets the current value of an engine property.
  • setProperty(name, value) – Queues a command to set an engine property. The new property value affects all utterances queued after this command.
  • say(text : unicode, name : string) – Queues a command to speak an utterance. The speech is output according to the properties set before this command in the queue.
  • runAndWait() – Blocks while processing all currently queued commands. Invokes callbacks for engine notifications appropriately. Returns when all commands queued before this call are emptied from the queue.

Simple demo:

import pyttsx3
engine = pyttsx3.init()
engine.say(" -Text to be spoken- ")
engine.runAndWait()

Above show about the library, why it can be used and how to install as well as use with a simple example.
