Compréhension audio

Présentation

Gemini peut analyser et comprendre des entrées audio, et générer des réponses textuelles. Il peut donc être utilisé dans les cas suivants :

Décrire, résumer ou répondre à des questions sur un contenu audio
Transcription et traduction (reconnaissance vocale)
Identification du locuteur
Détection des émotions dans la parole et la musique
Analyse de segments spécifiques avec des codes temporels

Pour les interactions vocales et vidéo en temps réel, consultez l' API Live. Pour les modèles de reconnaissance vocale dédiés compatibles avec la transcription en temps réel, utilisez l'API Google Cloud Speech-to-Text.

Transcrire la voix en texte

Cet exemple montre comment transcrire, traduire et résumer la parole avec des codes temporels, l'identification du locuteur et la détection des émotions à l'aide de sorties structurées.
