Improve Your Speech Recognition Models
Build or train your speech models in specific languages and domains or expand the scope with our high quality AI training datasets. Our expertise includes virtual or voice assistants, ASR, STT or TTS engines, call center IVR systems or vehicle infotainment assistants.
Monologue Speech Collection
Collect single speaker scripted, guided or spontaneous speech datasets, in broadband or narrowband.
Dialogue Speech Collection
Collect Agent and Caller or Caller and Bot interactions in guided or spontaneous speech datasets
Speech-to-Text Transcription
Our transcription workflows provide data collection, correction and validations to improve your STT system.
Speech Validation
Speech data is validated with our certified crowd incorporating inter-annotator agreements and gold sets.
Speech Quality Guarantee
Speech recognition systems require the highest quality AI training data to perform properly, otherwise, it will frustrate rather than delight. Our speech collection, transcription and validation workflows utilize a variety of ML algorithms and crowd quality checks that allow us to guarantee our quality.
Some of our quality metrics include:
Word Error RateSpeech dataset guarantee <5% for single speaker and <10% for multiple speakers |
Signal-to-Noise RatioControls dataset variation in background noise, ambient sounds, and other audio |
NativenessEnsures the datasets use native speakers for each language |
Text-Audio MatchHuman in the loop transcription validations check for exact matches |
