Svara.
Neural TTS
that sounds like the speaker.
Expressive text-to-speech with controllable prosody, voice cloning, and multi-speaker rendering. Sub-200ms first-byte latency for live agent assist and IVR replacement. Same binary across cloud, on-prem, and edge.
What enterprise TTS actually requires.
Sub-200ms first byte
Streaming synthesis emits the first audio packet before the sentence is fully composed. Built for live IVR replies, agent assist, and outbound voice agents.
Controllable prosody
Pace, pitch, emphasis, and emotion exposed as inline tags or per-utterance parameters. SSML-compatible. No black-box voice — engineers shape the read.
Voice cloning
Build a speaker profile from 30 seconds of consented audio. Useful for brand voices, multilingual narration, and personalization at scale.
Multi-speaker rendering
Render dialogues with distinct speakers in one pass. Useful for training data, audio drama, and synthetic conversation generation.
Code-switching
Speak Hindi-English mid-sentence with native prosody for both languages. Trained on real Indic call-center audio, not on dubbed corpora.
On-prem & edge
Same binary runs on Krsna SoC, NVIDIA, AMD, Intel, ARM. Quantized variants available for in-vehicle and embedded deployments.
Naturalness without the latency tax.
The bottleneck for production TTS isn't synthesis quality — it's the lag between request and first audible packet. Svara's streaming decoder and on-device-friendly architecture cuts first-byte latency without trading away naturalness.
Higher is better. Blind-scored by 30 listeners.
Methodology: 22kHz output, internal eval suite, blind MOS scored by 30 listeners. Latency measured wall-clock from request to first audio packet on L40s, FP16, batch-1.
Eighty-four studio voices. Plus your own.
Hear Svara in your brand voice.
A hosted voice playground with side-by-side A/B against your incumbent TTS is in private beta. Send us a script and a target voice profile — we'll return synthesized samples within 48 hours.
Bring a 30-second sample of consented audio for cloning, or pick a studio voice. We render the script and benchmark against your current TTS on naturalness and latency.
Email us a scriptDrop-in replacement for cloud TTS.
REST + WebSocket
SSML-compatible HTTP for batch jobs. Persistent WebSocket for streaming synthesis with sub-200ms first-byte latency.
Telephony adapters
8kHz µ-law and 16kHz PCM streams for Asterisk, FreeSWITCH, Genesys, Twilio. Drops into existing IVR replacement projects.
IRA bundled
Svara is the voice underneath every IRA agent. If you deploy IRA, Svara ships with it — no separate procurement, no second vendor.
