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:

Use the gTTS library to convert text into audio,
Split long texts automatically,
Combine multiple MP3 files into one, and
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:

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