OuteTTS
One-shot voice cloning TTS API with open weights on Hugging Face, billed per second generated.
For cloning a voice from a 10-second sample without a monthly commitment, OuteTTS is the most honest option we've priced: $10 per 10 credits billed per second, non-expiring credits, plus published GGUF/ONNX/FP8/EXL2 weights on Hugging Face is a combination closed vendors like ElevenLabs won't match. Buy a small credit pack first, because you pay before you hear the output. If a live phone agent is the target, latency-test against ElevenLabs Flash before you commit, and if you need a prebuilt connector catalog rather than an SDK, look elsewhere.

Skip OuteTTS if you need a prebuilt connector catalog, guaranteed low-latency live telephony out of the box, or a flat monthly rate for steady high-volume synthesis where per-second credits cost more.
You buy credit packs at $10 per 10 credits before hearing any output, so a voice that doesn't clone well on your sample leaves credits you still have to spend elsewhere.
At $10 per 10 credits billed per second with non-expiring credits, OuteTTS fits indie and early-stage teams whose volume swings month to month. Steady high-volume shops will find a flat monthly plan cheaper per unit, and teams that want a broad managed platform should price ElevenLabs or a cloud TTS service before committing.
In short
OuteTTS — One-shot voice cloning TTS API with open weights on Hugging Face, billed per second generated. Best for Developers shipping voice agents or IVR who need cloning without a training run, Indie teams who prefer per-second credits over a recurring monthly subscription, SaaS products with spiky week-to-week TTS volume. Plans from $10/10 credits.
What is OuteTTS?
OuteTTS — One-shot voice cloning TTS API with open weights on Hugging Face, billed per second generated. Best for Developers shipping voice agents or IVR who need cloning without a training run, Indie teams who prefer per-second credits over a recurring monthly subscription, SaaS products with spiky week-to-week TTS volume. Plans from $10/10 credits.
OuteTTS is a text-to-speech API built around one-shot voice cloning: hand it a 5-10 second clip and it reproduces that voice without a training run, then reads your text across 20+ languages. You buy credits at $10 per 10 credits and pay per second of audio generated, with credits that never expire, so a quiet month and a spiky one carry the same per-unit rate. A streaming endpoint handles real-time playback while a batch endpoint queues jobs for later, and an official Python SDK covers both sync and async. Studio, a no-code browser tool, handles prototyping and voice previews before you write code. Privacy is stated explicitly: input audio is discarded right after processing, samples are never stored or reused for training, session history can be deleted permanently, and API tokens are account-scoped and revocable. What separates OuteTTS from closed vendors is the weights — its Hugging Face organization publishes 32 models including Llama-OuteTTS-1.0-1B (updated Sep 8, 2025, about 2.4k downloads and 246 likes), the 1.0-0.6B family, the 0.3-1B line, and DAC-speech-v1.0-ONNX, with GGUF, ONNX, FP8 and EXL2-8bpw builds covering GPU, CPU and edge paths. That means you can start on the API and take the model in-house later, which closed TTS vendors rarely let you do.

Behind the verdict
OuteTTS occupies a narrow but useful slot: it is a pay-as-you-go voice cloning API whose models you can also download. Most hosted TTS vendors keep the model private and charge a subscription; OuteTTS publishes 32 models on Hugging Face, including Llama-OuteTTS-1.0-1B (updated Sep 8, 2025, roughly 2.4k downloads and 246 likes), ONNX, FP8, GGUF and EXL2-8bpw variants, plus DAC-speech-v1.0-ONNX for on-device speech decoding. If you build a voice agent on the API and later decide to self-host on a single GPU or an edge box, the weights are already there — that optionality is the strongest argument for choosing it. The API surface is thin by design. Streaming for real-time playback, batch for queued narration, an official Python SDK with sync and async support, and Studio for no-code prototyping and voice previews. Voice management is handled in a library of built-in and cloned voices. Privacy terms are unusually specific: input audio is discarded immediately after processing, samples are never stored or reused for training, session history can be deleted permanently, and API tokens are account-scoped and revocable. Where it falls short: the scraped evidence is a Hugging Face organization listing, so API ceilings, rate limits, character caps and which model variant serves a given request are not documented and cannot be verified. The math on choosing it is simple: if you synthesize sporadically, per-second credits at $10 per 10 credits with no expiry beat a flat subscription; if you run steady high volume, a monthly plan from a larger vendor will likely cost less per unit. And if latency is the product — a live phone agent where a pause is fatal — test it against ElevenLabs Flash before you commit, because a cold start is real.
Models under the hood
as of 2026-11-09
Limitations
- The public evidence is a Hugging Face organization listing, so API ceilings, rate limits, character caps and which model variant serves a given API request are not documented and cannot be verified from the live pages.
- You buy credits before you hear output, so quality on your specific speaker is unknown until you spend.
- The weights are distributed in 0.6B and 1B sizes (Llama-OuteTTS-1.0-1B, OuteTTS-1.0-0.6B and the 0.3-1B line) with GGUF, ONNX, FP8 and EXL2 builds, which is good for edge deployment but means quality is bounded by those model sizes rather than a frontier-scale model.
- The integration surface is deliberately thin — an HTTP API and a Python SDK — so any workflow glue is yours to write.

GeneratedReal-world workflow fit
Concrete scenarios for the personas OuteTTS actually fits — and what changes day-one when you adopt it.
Uploads a 10-second clip of their own voice, opens Studio to check it sounds right, then wires the streaming endpoint into a Python async agent using the official SDK.
Outcome: A working cloned-voice agent in a day, paid per second of audio with credits that don't expire.
Clones a narrator's voice once, then queues each lesson through the batch endpoint across 20+ languages instead of re-recording per locale.
Outcome: Course narration localized without a studio booking, with source audio discarded after processing.
Uses account-scoped, revocable API tokens and deletes session history, relying on the stated policy that input audio is discarded immediately and samples are never used for training.
Outcome: Voice output shipped without retaining customer audio, and an exit path to the open GGUF/ONNX weights if the vendor relationship changes.
Use cases
- Generate real-time voice responses for conversational AI agents
- Produce multilingual voiceovers for video across 20+ languages
- Clone a specific speaker's voice from a 10-second audio sample
- Automate batch narration of e-learning or audiobook content
- Add voice output to mobile apps through the HTTP API
- Prototype voice interfaces in Studio without writing code
- Run the open Llama-OuteTTS-1.0-1B weights in-house on your own hardware
Setup time & first value
How long it actually takes to get something useful out of OuteTTS — broken out by persona, not the marketing-page minute.
For a developer with an API key, first cloned audio is realistic in under an hour: one 5-10 second sample plus a streaming or batch call via the Python SDK. Studio gets a non-coder to a voice preview in minutes. Self-hosting the GGUF or ONNX weights is a separate, longer job that depends on your own GPU and serving stack.
Switching to or from OuteTTS
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ElevenLabs: swap the API call for OuteTTS's streaming or batch endpoint and re-clone each voice from a 5-10 second sample, since voice IDs don't carry over.
- →From a self-hosted OuteTTS model: start on the API with the same Llama-OuteTTS-1.0-1B family and move inference to the vendor's managed endpoints, or the reverse.
- →From Google or Amazon TTS: replace the vendor call with the Python SDK and re-record the target speaker's 10-second sample in place of a stock voice ID.
- ↗To self-hosted OuteTTS: download Llama-OuteTTS-1.0-1B in GGUF, ONNX, FP8 or EXL2-8bpw from Hugging Face and serve the same model family on your own hardware.
- ↗To ElevenLabs: re-clone your voices on their platform and use their SDK; expect to redo voice setup rather than port it.
- ↗To a cloud TTS service: map each cloned voice to a stock or custom voice and rewrite the SDK calls, since voice libraries are vendor-specific.
