Frequently asked questions

Can this find phrases without full transcription?

Yes. Picovoice's Speech-to-Index engine uses a phoneme-based approach to analyze audio, so it can detect voice matches without creating full-text transcripts. This allows users to locate key dialogue moments by sound alone, even if the exact wording or spelling is unknown. It's ideal for fast, private media searching where full transcription isn't practical.

Does it work for uncommon names or slang?

Yes. Since it relies on phonetic matching instead of strict text models, Dialogue Search can detect slang, names, and informal phrases—regardless of spelling. It's built to handle real-world speech patterns reliably.

How scalable is it for large media archives?

It's built to scale effortlessly. You can index once and then search across thousands of hours of media instantly—no need to regenerate indexes for each query. Whether you're managing a podcast archive, film catalog, or customer call recordings, search remains lightning-fast and cost-efficient, even as your content library grows.

Will I need cloud or special hardware?

No cloud infrastructure is required. Picovoice runs efficiently on desktops, browsers, and edge devices without needing GPUs—ideal for teams seeking full local control and deployment flexibility.
