Structured Conversational Voice Data
for Production AI Systems

Specialized datasets for Indian English, Hindi, and code-mixed speech.
Built with scenario-based prompt design, speaker balancing, and multi-pass QA.
Structured metadata for evaluation and fine-tuning.

What We Do

We provide structured voice and language datasets for production AI systems in Indian markets.

🎙️

Voice Datasets

Speech recognition and text-to-speech training data across Hindi, Hinglish, and Indian regional languages. Recorded in real-world conditions with demographic diversity.

  • Multi-speaker voice corpora
  • Accent and dialect coverage
  • Noise-variant recordings
  • Timestamped transcriptions
💬

Language Datasets

Text corpora for NLP, LLMs, and conversational AI. Culturally accurate, contextually rich, and cleaned for training.

  • Hindi, Hinglish, regional languages
  • Domain-specific corpora
  • Code-mixed conversations
  • Annotated for intent & entities
⚙️

Custom Data Collection

Need something specific? We build custom datasets to your exact specifications with defined QA processes and delivery timelines.

  • Tailored to your use case
  • Rapid deployment (weeks, not months)
  • Quality-checked at every stage
  • Flexible licensing terms

Why Sonexis Is Different

We are a precision-driven AI data partner focused on production-quality datasets.

Quality Over Scale

We don't sell volume. We sell data that works. Every dataset is human-verified, cleaned, and validated against production benchmarks. If it doesn't meet our bar, it doesn't ship.

Consent-First Sourcing

No scraped data. No grey-area collection. Every voice, every text sample is collected with explicit consent and documented usage rights.

Cultural & Linguistic Accuracy

Indian languages are not just translations of English. We understand code-mixing, regional variations, and cultural context. Our data reflects how people actually speak.

Built for Production AI

Our datasets are designed for real-world deployment, not research demos. We optimize for edge cases, demographic diversity, and the messy reality of production systems.

Scenario-Based Design

We design datasets around specific use cases and conversational scenarios. Speaker balancing across region and age ensures demographic representation.

Multi-Pass Quality Assurance

Every dataset goes through multi-pass transcription QA, noise labeling, and structured metadata creation for evaluation and fine-tuning.

Rapid Delivery

Custom datasets delivered on defined timelines. We move fast because we know your deployment schedules matter. Quality doesn't have to mean slow.

Clear Licensing

You own the data. Transparent licensing, documented rights, no platform dependencies. We're a data partner, not a vendor platform.

How We Design Data

Our methodology ensures production-ready datasets from day one.

Dataset Design Methodology

We begin with use case analysis and scenario mapping to define data requirements before collection begins.

Multi-Layer QA Structure

Three-stage verification: automated checks, human review, and production validation testing.

Structured Metadata Standards

Comprehensive metadata including speaker demographics, recording conditions, and linguistic annotations.

Consent Documentation Process

Recorded consent forms, usage rights documentation, and compliance tracking for every data point.

Speaker Balancing Protocol

Systematic representation across age, gender, region, and socioeconomic demographics.

Noise-Labelled Recording

Acoustic environments documented and labeled for robust model training.

Who It's For

If you're building AI that needs to work in India, we're built for you.

Foundation Model Teams

Training LLMs or multimodal models? Our Indian language corpora provide the linguistic diversity and quality your pre-training needs.

Speech AI Companies

Building ASR, TTS, or voice interfaces? Our voice datasets cover the accents, dialects, and acoustic conditions your models will face in production.

Ethics & Compliance

Data quality starts with data ethics. Here's how we do it:

Consent-Based Collection

Every data point is collected with explicit, informed consent. Contributors know exactly how their data will be used.

Clear Usage Rights

No ambiguity. You get clear, documented rights to use the data for AI training. No legal grey areas.

Ethical Sourcing

Fair compensation for contributors. No exploitative practices. No scraped or stolen data.

Privacy Protection

Personal identifiers removed. Data anonymized where required. Privacy protocols built into our collection process.
