Text-to-Speech

Convert text to natural-sounding speech

Text-to-speech models for voice apps, audiobooks, and IVR

Text-to-speech (TTS) models turn written text into natural-sounding spoken audio. The category covers everything from a flat IVR voiceover to expressive narration for audiobooks to realtime conversational agents that hold a phone call. Reach for a TTS model when you need to give software a voice — for accessibility, content production at scale, or conversational AI.

Pricing is almost always per-character or per-thousand-characters. Flagship neural voices (ElevenLabs V3, Cartesia Sonic, OpenAI TTS-HD) cost roughly €0.15-0.30 per thousand characters; budget tiers run under €0.02 per thousand. A typical short audiobook chapter (3,000 words, around 18,000 characters) costs €0.30-€5.00 depending on the tier you pick. Some providers also charge for voice cloning — a one-time fee to set up a custom voice plus the standard per-character rate at synthesis time.

The trade-off triangle is naturalness, latency, and cost. Flagship voices are nearly indistinguishable from human narration but typically have first-byte latency of 200-600ms, which is fine for batch synthesis but feels sluggish in realtime chat. Streaming TTS (Cartesia, OpenAI Realtime, ElevenLabs Turbo) keeps first-byte latency under 100ms by emitting audio as soon as the first phoneme is decoded. Budget tiers run at flagship speed but with audible robotic artifacts in long sentences.

Watch out for prosody control: even the best models occasionally mis-stress a proper noun, mispronounce an acronym, or lose emotional intent on long sentences. Use SSML tags (where supported) or break long passages into shorter chunks with explicit phrase boundaries. For multilingual content, verify pronunciation on every language pair before shipping — some voices speak English flawlessly and German with a heavy accent.

Top picks above cover the most natural-sounding voice, the cheapest workhorse, the longest-input-supporting model, and the fastest streaming option.
