Veena – Text-to-Speech Model
What is Veena?
Veena, developed by Maya Research, is a state-of-the-art text-to-speech (TTS) model built on a 3 billion-parameter Llama-based autoregressive transformer. It delivers natural, expressive speech in Hindi and English—handling mixed-language inputs seamlessly. Leveraging the SNAC neural codec at 24 kHz, Veena generates studio-quality audio with four distinct speaker personas (Kavya, Agastya, Maitri, Vinaya). Optimized for ultra-low latency (sub-80 ms on high-end GPUs) and production-ready deployment via 4-bit quantization, Veena is engineered for real-time applications in accessibility, customer service, content creation, and voice-enabled devices.
Key Features
- High-Fidelity Audio: 24 kHz sampling rate with SNAC neural codec for crystal-clear voice output
- Multilingual & Code-Switching: Fluent in Hindi and English; natural transitions in mixed-language text
- Four Unique Voices:
- Kavya (warm, friendly)
- Agastya (deep, authoritative)
- Maitri (clear, neutral)
- Vinaya (bright, youthful)
- Low Latency: Sub-80 ms response time on top-tier GPUs—ideal for live interactions
- Efficient Quantization: 4-bit precision reduces memory footprint without compromising quality
- Transformer-Based: 3 billion parameters capture complex intonation, stress, and pacing patterns
Best Use Cases
- Accessibility Tools: Screen readers, assistive communication devices
- Customer Service: Interactive voice response (IVR), chatbots, automated agents
- Content Creation: Podcasts, e-learning narrations, audiobooks
- Voice-Enabled Devices: Smart speakers, wearables, IoT interfaces
- Multilingual Platforms: Apps requiring seamless Hindi-English dialogue
Prompt Tips and Output Quality
- Input Text: For clarity, use simple, declarative sentences; combine complex phrases for emotional nuance.
- Speaker Selection (

FAQs
Can Veena handle Hindi-English code-switching?
Yes. Veena’s transformer backbone is trained on mixed-language corpora for seamless transitions.
What latency should I expect in production?
On high-end GPUs, Veena delivers sub-80 ms end-to-end latency—perfect for real-time use.
How do I pick the best speaker voice?
Choose based on your brand or application tone: Kavya for warmth, Agastya for depth, Maitri for neutrality, Vinaya for energy.
Is a quantized version available?
Absolutely. Veena supports 4-bit quantization for reduced memory usage and faster inference.
What sample rate does Veena output?
Audio is synthesized at 24 kHz using the SNAC neural codec for smooth, high-quality playback.
