Frequently Asked Questions

Everything about Text-to-Speech API

What is a text-to-speech API?

A text-to-speech (TTS) API converts written text into natural-sounding speech audio. It's used for voice assistants, IVR systems, audiobooks, accessibility features, e-learning, and video narration. Our API provides access to multiple TTS providers with 200+ voices through a unified interface.

Which TTS providers do you support?

We support 8+ TTS providers: Google Cloud TTS (multilingual), Azure Neural (enterprise), ElevenLabs (most natural), OpenAI TTS (cost-effective), Deepgram Aura (low latency), Cartesia (real-time), Sarvam AI (Indian languages), and PlayHT. Choose based on voice quality, language, and cost.

What Indian language voices are available?

We offer HD voices for 10 Indian languages: Hindi (male & female), Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, and Assamese. Azure Neural provides the most natural Indian voices with expressive styles. For Hindi, we recommend Azure voices like 'SwaraNeural' and 'MadhurNeural'.

What is real-time streaming TTS?

Real-time streaming TTS generates audio chunk-by-chunk as text is processed, reducing time-to-first-byte. Instead of waiting for the entire audio file, you get audio within milliseconds. Essential for voice assistants and conversational AI where low latency matters.

How natural do the voices sound?

Modern neural TTS voices are nearly indistinguishable from human speech. ElevenLabs leads in naturalness with emotional expression. Azure Neural and Google WaveNet offer high-quality voices. For the most natural experience, we recommend ElevenLabs for English and Azure Neural for Indian languages.

What is voice cloning?

Voice cloning creates a custom TTS voice that sounds like a specific person. ElevenLabs offers instant voice cloning from ~1 minute of audio, and professional voice cloning from ~30 minutes of studio recordings. Useful for brand voices, audiobooks by authors, and personalized assistants.

What is SSML and do you support it?

SSML (Speech Synthesis Markup Language) is an XML-based language for controlling speech output - pauses, emphasis, pronunciation, speed, and pitch. All our providers support SSML tags. Use SSML for precise control over how text is spoken.

How much does TTS cost?

Pricing is per character: Google from $0.000004/char, Azure $0.000016/char, OpenAI $0.000015/char, ElevenLabs from $0.00003/char (premium quality). A typical 1-minute audio (~150 words, ~750 chars) costs $0.003-$0.02 depending on provider.

What audio formats are supported?

We support all common formats: MP3 (most compatible), WAV (highest quality), OGG (efficient), PCM/mulaw (telephony). Sample rates from 8kHz (phone) to 48kHz (studio). For voice assistants, we recommend mulaw/8kHz for Twilio and PCM/16kHz for others.

Can I create custom branded voices?

Yes! ElevenLabs offers professional voice cloning for custom branded voices. Azure Custom Neural Voice creates enterprise-grade custom voices. These require audio samples and training time but result in unique voices for your brand.
