Children (including pre-pubescent children with different vocal characteristics) 2. Korean-English code-switching (natural language mixing in a single sentence) Traditional STT services are trained primarily on adult voices and single-language speech, achieving less than 80% accuracy for children and failing completely on code-switched speech. Theta One's proprietary deep learning models solve these challenges with 95%+ accuracy across all user types.
