Once the words are captured, these features help you understand, organize, and act on the content — from instant translation to key-point summaries, entity detection, chapter markers, emotions, and even custom LLM prompts. Detect speakers and understand who said what, and when. Translate transcripts and subtitles into multiple languages in one request. Automatically redact names, emails, vehicle IDs, and other PII in pre-recorded transcripts. Generate ready-to-use subtitle files in SRT or VTT formats. Boost recognition accuracy for specific terms. Generate concise summaries or bullet points for quick understanding. Detect and categorize key entities like people, organizations, dates, and more. Segment long audio into chapters with headlines and summaries for easy navigation. Understand the tone and emotions expressed across the transcript. Ask custom questions and run prompts on your audio like an assistant would.
