The API is designed to handle multilingual scenarios by allowing language detection and code-switching, and it offers automatic translation with contextual and tonal adjustments. Additional capabilities include speaker diarization to distinguish multiple speakers in recordings and live message stream control for real-time feedback. Users are encouraged to follow best practices for evaluating transcription accuracy, using metrics such as Word Error Rate (WER) and ensuring reliable reference data. Overall, Gladia's API aims to deliver fast, accurate, and flexible transcription solutions, with support available for integration and optimization.
