Understanding Audio Transcription via Gemini APIs

Gemini models are multimodal large language models. They can process and generate various types of data, including text, code, images, audio, and video. Gemini models also offer powerful audio transcription capabilities, enabling developers to convert spoken content into text. This can help in building a transcription service, creating subtitles for videos, and developing voice-enabled applications. If you are looking to convert speech to text using Gemini’s powerful AI models, this comprehensive guide will show you how to implement audio transcription using different Gemini APIs. We will go from basic implementation to advanced real-time streaming.

Gemini supports the following audio formats as input: WAV, MP3, AIFF, AAC, OGG, and FLAC. We will look at generateContent, streamGenerateContent, and BidiGenerateContent(LiveAPI) APIs. You can find all supported APIs at https://ai.google.dev/api. generateContent is a standard REST endpoint, which processes the request and returns a single response. streamGenerateContent uses SSE (server-sent-events) to send partial responses as they are generated. This API is a better choice for applications like chatbots, which need a faster and more interactive experience.
