Amazon Transcribe is an automatic speech recognition (ASR) service that makes it easy for you to add speech-to-text capabilities to your applications. Today, we are excited to announce automatic language identification support for multi-lingual audio in batch mode. If your audio recording contains more than one language, you can enable multi-language identification, which identifies all languages spoken in the audio file and creates transcript using each identified language. This means that if speakers change languages mid-conversation, or if each participant is speaking a different language, your transcription output detects and transcribes each language correctly. Until now, Transcribe would detect the dominant language in the audio recording and generate transcriptions in the identified language. You can now simply provide the audio files and Transcribe will detect the language from the speech signal and generate transcriptions in the identified language.
