Specify the population
Define languages, variants, speakers, environments, tasks, rights, metadata, and coverage targets.
TTS & STT
Speech data programs
Speaker, prompt, recording, transcription, and validation systems for multilingual speech development.
The challenge
Speech datasets encode their collection choices. Unbalanced speakers, unnatural prompts, poor environments, and inconsistent transcription create model limits that are hard to repair later.
We design the data program around the model task and the population it must serve. Language, demographic, acoustic, and legal requirements become operational collection rules.
Quality is monitored throughout recruitment, recording, transcription, and delivery rather than inspected only at the end.
How we work
Evidence first. Decisions visible. Knowledge transferred.
We adapt the depth and sequence to your product stage, language scope, and internal team.
Run the collection
Design prompts, recruit and guide speakers, control recordings, transcribe, and monitor field quality.
Validate the corpus
Audit coverage, signal quality, transcripts, duplicates, consent, metadata, and model suitability.
Typical outputs
