Meeting bot speech recognition: how real-time transcription powers automated meeting assistants

Meeting bot speech recognition technology hinges on achieving sub-300ms latency for speech-to-text (STT) processes, real-time speaker diarization, and code-switching to maintain reliability, especially in multi-speaker environments like Zoom or Teams. Effective transcription infrastructure is crucial, as production meeting bots often fail due to challenges such as multi-speaker overlap and language switching, which can lead to inaccurate speaker attribution and unreliable transcripts. Managed STT APIs like Gladia offer a solution by providing real-time transcription with built-in diarization and support for over 100 languages, ensuring enterprise compliance and data privacy. The complexity of building a meeting bot lies in capturing and processing raw audio efficiently while maintaining a low Real-Time Factor (RTF) to ensure responsive interaction. Evaluating transcription quality goes beyond standard Word Error Rate (WER) metrics, requiring consideration of Diarization Error Rate (DER) and Word-level Diarization Error Rate (WDER) to accurately capture speaker attribution and semantic impact. Managed solutions are often more cost-effective than self-hosting options like Whisper, which require significant infrastructure and maintenance resources. Gladia's API supports real-time diarization and speaker identification, offering a robust infrastructure layer for automated meeting assistants without competing product interests, and is designed to safeguard sensitive meeting data through compliance with SOC 2 and HIPAA standards.
