Best Text to Speech APIs Compared (2026)

Why Use a TTS API?

If you're building an app that needs voice — read-aloud features, voice assistants, notification systems, accessibility tools — you need a TTS API. Here's how the top options compare in 2026.

Quick Comparison

EasyVoice API

**Best for:** Developers who want cheap, unlimited TTS with an OpenAI-compatible endpoint.

from openai import OpenAI

client = OpenAI(

api_key="ev_your_key",

base_url="https://easyvoice.dev/api/v1"

)

response = client.audio.speech.create(

model="kokoro-82m",

voice="af_aoede",

input="Hello from EasyVoice!"

)

response.stream_to_file("output.mp3")

**Pros:** Cheapest unlimited plan ($9.99/mo), OpenAI-compatible, open source engine

**Cons:** 54 voices (fewer than some competitors), no voice cloning yet

ElevenLabs API

**Best for:** Projects that need the highest quality voices or voice cloning.

**Pros:** Best voice quality, voice cloning, 100+ voices

**Cons:** Expensive ($5-$99/mo for limited characters), not OpenAI-compatible

OpenAI TTS

**Best for:** Projects already using OpenAI's API.

**Pros:** Simple, high quality, native OpenAI SDK

**Cons:** Only 6 voices, pay-per-use ($15/1M chars), no free tier

Our Recommendation

**Budget-conscious:** EasyVoice ($9.99/mo unlimited)

**Highest quality:** ElevenLabs (but expensive)

**Already using OpenAI:** Stick with OpenAI TTS, or switch to EasyVoice to save money

**Enterprise scale:** Google Cloud or Amazon Polly (pay-per-use)
