ENFrequently Asked Questions
Bark is a transformer-based text-to-audio model created by Suno. Unlike traditional TTS systems, Bark generates highly expressive speech with natural emotions, laughter, sighs, and other non-verbal sounds. It can even generate music and sound effects.
Yes, Bark is open-source under the MIT license, allowing free commercial use. On TextToSpeechAI, we charge 25 credits per 1000 characters due to the significant GPU resources required for generation.
Bark supports 13+ languages including English, German, Spanish, French, Hindi, Italian, Japanese, Korean, Polish, Portuguese, Russian, Turkish, and Chinese. Each language has natural pronunciation and accents.
Bark is slower than most TTS engines due to its autoregressive transformer architecture. A typical sentence takes 5-15 seconds to generate on GPU. The tradeoff is significantly more expressive and natural output.
Bark has limited voice cloning through "semantic prompts" - you can use speaker presets but cannot easily clone arbitrary voices. For full voice cloning, use StyleTTS2, F5-TTS, OpenVoice, or Tortoise instead.
Use emotion markers in your text: [laughter] for laughs, [sighs] for sighs, [gasps] for gasps, ... for hesitation, CAPS for emphasis. Example: "Oh wow! [laughter] This is AMAZING... I can't believe it!"
Bark produces very good quality audio with natural expressiveness that rivals human speech for emotional content. The 24kHz output sounds professional, though pure speech quality is slightly below StyleTTS2.
Bark requires 8-12GB of VRAM depending on model size. The full model needs ~12GB, while smaller variants work with 8GB. CPU inference is extremely slow and not recommended.
Yes, Bark is MIT licensed which permits unrestricted commercial use. You can use it in products, services, and applications without licensing fees.
Select a Bark voice from our voice library and include emotion markers in your text. The API processes your request and returns expressive audio with the emotions you specified.
Bark outputs WAV audio natively. Through TextToSpeechAI, you can request MP3, WAV, or OGG formats. We handle format conversion while preserving the expressive qualities.
Bark is unique in its ability to generate genuinely expressive speech with emotions and non-verbal sounds. It is slower than other engines but produces more human-like results for creative content. For faster synthesis, use Piper. For voice cloning, use F5-TTS or OpenVoice.
