Frequently Asked Questions

Is KAZI AI Voice Synthesis free to use?

How many voices does KAZI support?

KAZI currently offers 46+ AI voices across OpenAI TTS and ElevenLabs providers. OpenAI provides high-quality voices like Alloy, Echo, Fable, Onyx, Nova, and Shimmer across multiple models. ElevenLabs adds dozens more with multilingual support and voice cloning capabilities.

Can I clone my own voice?

Yes. Upload a 30-second audio sample of clear speech and KAZI will create a custom voice clone via ElevenLabs. Once trained, use your cloned voice across all projects for consistent, branded narration without re-recording.

What languages are supported?

ElevenLabs eleven_multilingual_v2 supports 50+ languages including English, Spanish, French, German, Italian, Portuguese, Hindi, Arabic, Japanese, Korean, and many more. OpenAI TTS also supports multiple languages automatically based on input text.

How much does it cost?

KAZI uses a pay-per-use model with BYOK (Bring Your Own Key): you pay OpenAI or ElevenLabs directly at their standard rates with zero KAZI markup. Alternatively, use the free browser-native TTS fallback for zero-cost synthesis powered by the Web Speech API.

What audio formats are supported?

KAZI supports six export formats: MP3, WAV, FLAC, Opus, AAC, and PCM. MP3 is ideal for podcasts and web content, WAV and FLAC for professional editing and lossless archival, Opus for efficient streaming, AAC for broad device compatibility, and PCM for raw uncompressed audio.

Can I use voice synthesis in other KAZI modules?

Yes. Over 12 KAZI modules include a "Read Aloud" feature powered by the same voice synthesis engine. Use it in the AI Chat, Documents, Proposals, Invoices, Projects, and more to listen to any text content hands-free.

Is there an API?

Yes. KAZI provides a full REST API with streaming support for voice synthesis. Generate audio programmatically, manage voice settings, and retrieve generation history, all with the same BYOK pricing and provider flexibility as the dashboard.

How does voice cloning work?

Upload a short audio sample (at least 30 seconds of clear speech) and KAZI will train a custom voice model via ElevenLabs. Once ready, use it across all your projects for consistent branded narration.

Which AI providers power the voices?

KAZI integrates OpenAI TTS (tts-1, tts-1-hd, gpt-4o-mini-tts models) and ElevenLabs (multilingual v2, flash v2.5, turbo v2.5 models). You can switch providers per generation to compare quality and cost.

What are emotion presets?

Emotion presets adjust pitch, pacing, and emphasis to match your content tone. Choose from Neutral, Expressive, Dramatic, Calm, or Energetic to set the delivery style without manual parameter tuning.

Can I track how much I spend on voice generation?

Absolutely. Every generation logs the provider, model, character count, and estimated cost. The analytics dashboard shows total spend, usage trends, and per-provider breakdowns over any time range.

Can I share generated audio with clients?

Yes. Every synthesis gets a shareable public link that anyone can open to listen, download, and view metadata. No KAZI account required.
