About David AI
Contact SalesAdvancedNo API
David AI is an audio data research company that creates high-quality datasets specifically designed for speech recognition, translation, synthesis, conversational AI, and voice interaction systems. Their datasets are used by Fortune 100 companies and research labs. The company follows a rigorous six-step process—Hypothesize, Design, Experiment, Evaluate & Iterate, Productionize, Release—to develop datasets with the same rigor researchers bring to models. They offer several featured datasets: Converse (natural two-speaker conversations), Atlas (multilingual with 15+ languages), Chorus (three or more speakers), and Dialog (expert conversations across domains). Access is obtained by requesting samples, then entering a data license agreement. David AI also partners with research teams to design custom datasets. Compared to public datasets or data marketplaces, David AI offers a scientific approach to data curation and custom dataset design, but its lack of transparent pricing and API access makes it inaccessible for small teams or individual developers.
Behind the Verdict
David AI stands out for its scientific, research-driven approach to dataset creation, treating data with the same rigor as models. Its six-step process and featured datasets (Converse, Atlas, Chorus, Dialog) are tailored for training speech-to-speech, multilingual, and voice interaction systems. The company's recent $50M Series B (October 2025) and $25M Series A (May 2025) signal strong investor confidence and resources for scaling. However, the lack of transparent pricing, self-service access, or API means that evaluation requires a sales conversation, making it impractical for individual developers, early-stage projects, or teams needing rapid prototyping. Compared to public datasets or marketplaces like Hugging Face, David AI offers curated, high-signal data with metadata (dialects, accents, speaker separation) but at a higher cost and longer lead time. It excels for Fortune 100 companies and research labs with dedicated budgets, but not for low-resource teams.

Real-world workflow fit
Concrete scenarios for the personas David AI actually fits — and what changes day-one when you adopt it.
Research scientist at a Fortune 100 company
You need a multilingual dataset with dialect metadata to train a voice assistant for a global product.
Outcome: Request Atlas samples, sign a license, and receive the dataset within two days to begin training.
CTO of a startup building a speech-to-speech translation app
You require channel-separated two-speaker conversations for training a real-time translation model.
Outcome: Contact David AI, evaluate Converse samples, negotiate a license, and integrate the data into your pipeline.
Academic researcher in speaker diarization
You need multi-speaker audio with ground truth for evaluation.
Outcome: Request Chorus samples, access the dataset via institutional license, and publish results using high-quality benchmarks.
Use Cases
- Train speech recognition models on diverse natural conversation data
- Build multilingual voice assistants with coverage across 15+ languages
- Improve speaker diarization using three-plus speaker audio
- Develop domain-specific conversational AI with expert dialog datasets
- Enhance speech-to-speech translation systems with channel-separated audio
Limitations
- Pricing and dataset access require contacting sales, with no self-service options.
- There is no public API or free tier, making evaluation difficult without a prior relationship.
- Datasets are proprietary and not available for immediate download without a license agreement.

Where the pricing makes sense
The company stage and team size where David AI's pricing actually pencils out — and where peers do it cheaper.
David AI targets enterprise and research teams with dedicated budgets for high-quality audio data. Competitors like public datasets (LibriSpeech, Common Voice) are free but lack curated quality and metadata. Custom data solutions from vendors like Appen or Defined.ai may offer similar services but often with less scientific rigor in dataset design.
Setup time & first value
How long it actually takes to get something useful out of David AI — broken out by persona, not the marketing-page minute.
For off-the-shelf datasets, sample requests take a day via a call, then data access is granted within one to two days after signing a license. Custom dataset design timelines vary based on scope.
Switching to or from David AI

Migrating in
- →From public datasets (e.g., LibriSpeech, Common Voice): Replace with David AI datasets for higher quality and metadata richness; contact sales to transition.
Migrating out
- ↗To in-house data collection: Use David AI's methodologies as a reference for designing your own pipeline.
- ↗To crowdsourced data platforms (e.g., Appen, Defined.ai): Similar licensing model but less scientific process.
