How to Use Google Text-to-Speech API for Free (with Python)


🧠 Introduction

Text-to-Speech (TTS) technology allows you to convert any text into a human-like voice.

While many platforms charge for API access, Google’s Text-to-Speech API (gTTS) offers a completely free and easy way to generate realistic voices using Python.

In this article, you’ll learn how to:

  1. Use the gTTS library to convert text into audio,
  2. Split long texts automatically,
  3. Combine multiple MP3 files into one, and
  4. Play or download your generated speech.


⚙️ Step 1: Install Required Libraries


Let’s start by installing the Python packages:

pip install gtts
pip install pydub

gtts handles speech generation, and pydub helps merge multiple audio parts.


💬 Step 2: Example Code to Generate Speech


import os
from gtts import gTTS
from pydub import AudioSegment

def split_text(text, max_length=2000):
return [text[i:i + max_length] for i in range(0, len(text), max_length)]

input_file = "./sample_data/1.txt"
with open(input_file, "r", encoding="utf-8") as file:
text = file.read()

if not text.strip():
print("Input file is empty.")
exit()

language = 'en'
parts = split_text(text)

output_files = []
for i, part in enumerate(parts):
filename = f"output_part_{i}.mp3"
tts = gTTS(text=part, lang=language)
tts.save(filename)
output_files.append(filename)

# Combine all parts
combined_audio = AudioSegment.empty()
for file in output_files:
combined_audio += AudioSegment.from_file(file)

final_filename = "output_combined.mp3"
combined_audio.export(final_filename, format="mp3")
print(f"Final audio saved as {final_filename}")

This script:

  1. Splits your text into chunks,
  2. Generates each part with Google TTS,
  3. Combines all audio files into one clean MP3 file.
