GPT-4o-transcribe is an OpenAI model for speech-to-text conversion, developed as an upgrade to the Whisper model, with a focus on improving transcription accuracy and reducing the word error rate. It supports over 100 languages and works in environments involving noise, different accents, and varying speech rates; it also incorporates techniques for noise reduction and semantic speech activity detection. The model supports real-time speech-to-text conversion, allowing for continuous audio input and real-time text output. It can be used in call centers, for creating meeting minutes, in smart assistants, and in applications that require voice interaction.
