Frequently asked questions

Can I run phonetic search without full transcription?

Yes. Picovoice's Speech-to-Index engine enables phonetic search by creating audio fingerprints, allowing you to find specific phrases in hours of legal recordings without converting them into full transcripts. This accelerates discovery workflows while preserving privacy and reducing computational overhead.

How is privacy guaranteed?

All audio processing—transcription, indexing, and search—occurs entirely on your local infrastructure. Voice data and transcripts are never sent to external servers during use, helping you meet confidentiality and compliance requirements.

What are the hardware requirements?

The engine runs on common server or desktop configurations—no need for GPUs or cloud compute resources. It's also scalable across multiple machines for high-volume audio review, making it ideal for law firms, compliance teams, and digital forensics professionals managing large-scale discovery efforts.

What platforms are supported?

Picovoice supports Windows, Linux, macOS, and embedded Linux environments. This makes it deployable across enterprise servers, on-premise legal tools, and portable forensic kits, offering flexibility for e-discovery teams wherever they operate.
