About

Gemini 3.5 Transcribe is Google’s most precise speech-to-text model yet, designed for intelligent voice interactions and real-time transcription. Instead of simply converting speech word for word, it turns raw audio into accurate, polished, formatted text while handling background noise, complex jargon, accents, dialects, and natural speaking patterns. Smart transcription automatically understands self-corrections, removes filler words such as “ums” and “ahs,” and formats the final text for readability. The model supports continuous bidirectional streaming with sub-second latency for interactive voice applications, as well as pre-recorded audio processing for meetings, call logs, and other recordings with speaker attribution and word-level timestamps. Custom vocabulary helps it recognize specialized terminology, unique spellings, postal codes, order IDs, and other domain-specific language.

About

Inworld Realtime STT is a realtime streaming STT API that understands users beyond their words. It combines low-latency speech recognition with voice profiling, extracting emotion, vocal style, accent, age, and pitch directly from raw audio so downstream LLMs and TTS systems can respond with more adaptive, expressive behavior. Developers can stream audio in real time, transcribe complete files, or extract voice profile signals through one unified API, with realtime bidirectional streaming over WebSocket, synchronous transcription for full audio files, voice profile signals on every streaming chunk, and multi-provider support through a single model ID. Every audio chunk can produce a realtime profile of the speaker with confidence scores, giving LLMs structured context such as whether a user sounds sad, frustrated, soft, high-pitched, or calm.

Pros & Cons from Real Users

Pros

  • It is designed for cleaner, more intelligent transcription, including handling filler words, corrections, language switches, and more natural voice input. For developers, the live model is the biggest draw. Low-latency streaming transcription opens up a lot of useful product ideas: meeting tools, support call notes, voice agents, accessibility features, medical dictation, creator tools, and real-time captions. I also like that it is exposed through the Gemini API and Google AI Studio, so it is not just a feature buried inside a Google app. Developers can actually build with it directly.

Cons

  • I would want to test it across noisy environments, accents, domain-specific vocabulary, and long calls before trusting it in production. Transcription models can look great in demos but struggle when audio quality gets messy.
