Best AI Voice Generators in 2026 (4 Models Compared, With Prices)

Bolly has four AI voice models: ElevenLabs v3 for text to speech with the widest language coverage, Qwen Audio 3 TTS for the lowest price (2 credits per 1,000 characters), Voice Designer to describe a new voice in words, and Voice Changer to re-voice a recording you already have. None of them clones a voice from a sample. The three text-to-speech models run on the Free plan's 10 daily credits; Voice Changer costs 12 credits a run, which is more than a Free day, so it needs a paid plan in practice.

Bolly's voice library has four models that do three different jobs. ElevenLabs v3 and Qwen Audio 3 TTS read your script aloud in a voice you pick from a menu. Voice Designer reads it in a voice you describe in words. Voice Changer starts from a recording instead of a script and swaps the speaker's voice while keeping the delivery. Sound effects, transcription and vocal isolation are separate audio tools and are not part of this list.

None of the four clones a voice. There is no step where you upload a sample and get a copy of it back, and this page does not pretend otherwise. Voice Changer takes a real recording, so Bolly's consent rules apply to it: use only your own voice or the voice of someone who has clearly agreed, never to impersonate anyone, deceive people or get past a voice-based security check, and never upload a recording of anyone under 18. When you share realistic AI audio, say that it is AI-generated.

The order is editorial. It puts the jobs most people search for first, then language and voice coverage, price and what runs on the Free plan. It is not a ranking of audio quality, which only your own ears can judge on your own script. Credits are Bolly's estimates at default settings (1 credit ≈ $0.05). Text-to-speech runs are priced per 1,000 characters and Voice Changer per run; the composer shows the price before you run, and a failed run is refunded.

The 4 best ai voice generators, ranked

1.ElevenLabs v3by ElevenLabs
4 credits / run · Free plan
The broadest language coverage of the four, plus emotion and delivery tags and 21 named voices.
Best for: Voiceovers, narration and ads, especially in languages Qwen Audio 3 TTS does not cover. Modes: Text to speech.
- 70+ languages according to ElevenLabs' documentation (as of Sep 29, 2026), against 10 for Qwen Audio 3 TTS and Voice Designer
- 21 named voices (Rachel is the default) and a Stability setting from 0 to 1, default 0.5, under advanced settings
- Emotion and delivery tags: Bolly's description lists them, and ElevenLabs' prompting guide includes audio tags among the techniques that apply to v3 (as of Sep 29, 2026)
- An optional language code (ISO 639-1, such as es) forces the language instead of leaving it to the model
- 4 credits (about $0.20) per 1,000 characters, twice Qwen Audio 3 TTS, and 8 credits (about $0.40) for a script of 1,001 to 2,000 characters
- Built-in voices only: there is no way to upload a sample and clone a voice
- ElevenLabs' documentation lists a 5,000-character limit for Eleven v3 (as of Sep 29, 2026), so split long scripts, and it also lists a newer Eleven v4 that Bolly does not offer
Try ElevenLabs v3
2.Qwen Audio 3 TTSby Alibaba
2 credits / run · Free plan
The cheapest way to turn text into speech on Bolly, with 45 voices and 10 languages for 2 credits per 1,000 characters.
Best for: Long scripts, drafts and bulk narration where price per run matters more than fine control. Modes: Text to speech.
- 2 credits (about $0.10) per 1,000 characters, half the price of ElevenLabs v3, so a 10-credit Free day covers five runs of up to 1,000 characters
- 45 named voices to choose from (Cherry is the default)
- Ten languages plus Auto: Chinese, English, Spanish, Russian, Italian, French, Korean, Japanese, German and Portuguese; naming the language yourself improves pronunciation and intonation, according to the setting's description
- Ten languages, against the 70+ ElevenLabs lists for v3 (as of Sep 29, 2026)
- Bolly exposes only three settings, text, language and voice, so there is nothing like ElevenLabs v3's stability setting
- The voice menu lists names without descriptions, so finding the right voice means trying a few
Try Qwen Audio 3 TTS
3.Voice Designerby Qwen
4 credits / run · Free plan
The only model here where you describe the voice you want in words instead of picking one from a menu.
Best for: One-off characters and narrators that a preset voice list does not offer. Modes: Design voice.
- Describe the voice in the optional Prompt field (the setting's description says it guides the style of the speech) and write the script in Text
- Runs on the Free plan: 4 credits (about $0.20) covers up to 1,000 characters, so two runs fit in a 10-credit day
- Ten languages plus Auto, and advanced sampling settings (temperature, top-p, top-k, repetition penalty) for anyone who wants to tune it
- Sampling is random by default (temperature 0.9, and higher means more random), so two runs of the same description may not sound identical
- Max new tokens defaults to 200 (the limit is 8,192), and that cap may cut a long script short unless you raise it in advanced settings
- Twice the price of Qwen Audio 3 TTS for a script of up to 1,000 characters: 4 credits against 2
Try Voice Designer
4.Voice Changerby ElevenLabs
12 credits / run · Free plan
The one tool here that starts from your own recording: Bolly describes it as keeping the timing, emotion and delivery while the voice changes.
Best for: Recordings you have already made where the delivery is right but the voice is not. Modes: Change voice.
- An optional switch removes background noise from the uploaded audio (off by default)
- Output as MP3 at several bitrates, PCM, Opus, mu-law or A-law (default MP3, 44.1 kHz, 128 kbps)
- A seed setting for reproducible results
- A flat 12 credits (about $0.60) per run, and it is listed as a Free-plan model, but that is more than the 10 credits a Free account gets each day, so in practice you need a paid plan's monthly credits
- The voice is a plain text box (default Rachel), not a menu, and it changes a voice rather than cloning one
- Real voices need consent: use only your own voice or a speaker who has clearly agreed, and never a recording of anyone under 18

Frequently asked questions

What is the best AI voice generator?

It depends on the job. For a script in many languages, ElevenLabs v3 (70+ languages according to ElevenLabs' documentation, as of Sep 29, 2026). For the lowest price, Qwen Audio 3 TTS at 2 credits per 1,000 characters. For a voice you describe instead of pick, Voice Designer. For changing the voice in a recording you already have, Voice Changer. Bolly hosts all four on one credit balance, so you can run the same script through two of them and keep the one that sounds better to you.

Is there a free AI voice generator?

Bolly's Free plan gives 10 credits a day, reset at midnight UTC, and it runs ElevenLabs v3 (4 credits), Qwen Audio 3 TTS (2 credits) and Voice Designer (4 credits) for scripts of up to 1,000 characters. That is about five Qwen runs or two ElevenLabs or Voice Designer runs a day. Voice Changer costs 12 credits, more than a Free day, so it needs a paid plan in practice. Generations on the Free plan are public, and private generations need a paid plan, so Free suits trying voices more than producing confidential or high-volume audio.

Can I clone my voice with Bolly?

No. Bolly has no voice-cloning model, and none of the four takes a sample of a voice and builds a copy of it. Voice Designer makes a new voice from a written description, and Voice Changer re-voices a recording into a named voice. Whatever you use, work only with your own voice or the voice of someone who has clearly agreed, and never use a voice to impersonate someone, deceive people or get past a voice-based security check.

How much does an AI voiceover cost on Bolly?

Text to speech is priced per 1,000 characters, rounded up, with a minimum of one step. Qwen Audio 3 TTS costs 2 credits (about $0.10) per step and ElevenLabs v3 costs 4 credits (about $0.20). A 5,000-character script is 10 credits (about $0.50) on Qwen and 20 credits (about $1) on ElevenLabs v3. Voice Designer is 4 credits (about $0.20) for up to 1,000 characters and 18 credits (about $0.90) for 5,000, and Voice Changer is a flat 12 credits (about $0.60) per run. As a rough guide, 1,000 characters is 150 to 200 English words, about a minute of speech. One credit is about $0.05, and a failed run is refunded.

Which languages do the voices support?

Qwen Audio 3 TTS and Voice Designer offer the same ten languages plus Auto: Chinese, English, Spanish, Russian, Italian, French, Korean, Japanese, German and Portuguese. ElevenLabs v3 lists 70+ languages in ElevenLabs' documentation (as of Sep 29, 2026), and its optional language code (ISO 639-1) forces one. On Qwen, naming the language instead of leaving it on Auto improves pronunciation and intonation, according to the setting's description. In any language, listen for names, numbers and technical terms before you use the audio.

What is the difference between text to speech and a voice changer?

Text to speech starts from written text and generates the speech itself. A voice changer starts from a recording of someone speaking and keeps their timing, emotion and delivery while swapping the voice. On Bolly, ElevenLabs v3, Qwen Audio 3 TTS and Voice Designer are text to speech, and Voice Changer processes an audio file you upload and returns a new file. It is not a live voice changer for calls or games.

How long can a script be?

Bolly prices text to speech per 1,000 characters, so length mostly affects cost. ElevenLabs' documentation lists a 5,000-character limit for Eleven v3 (as of Sep 29, 2026), so split a longer script into parts and use the same voice and settings for each. In Voice Designer, the Max new tokens setting defaults to 200 and goes up to 8,192; raise it if a long script comes back cut short.

How do I pick a voice without wasting credits?

Pricing has a one-step minimum, so a single sentence costs the same as 1,000 characters. Audition voices with the first 1,000 characters of your real script instead: 2 credits on Qwen Audio 3 TTS, 4 on ElevenLabs v3 or Voice Designer. On a Free day that is about five Qwen tries or two ElevenLabs tries. Audition on the model you plan to use, since each model has its own voice list.

Can I use the audio in videos, ads or a podcast?

Bolly's Terms say that, as between you and Bolly and as far as the law allows, you own what you generate. They do not promise that outputs are protectable or unique, and they say some models carry extra terms from their developers, such as limits on commercial use. Check the Terms and any developer terms Bolly shows for the model before commercial use. If you share realistic AI audio, say that it is AI-generated and use your platform's AI labels.
