What Picovoice Leopard is
Picovoice Leopard is an on-device speech-to-text engine for transcribing audio and video files, including recordings of interviews, meetings, calls, podcasts, and voicemails. Picovoice says the inputs and generated outputs remain on the device and are not transmitted to or accessible by the company or its service providers. Transcripts can include word start and end times, confidence scores, and speaker tags. Developers can use Picovoice Console to add custom vocabulary and raise the likelihood of selected words and phrases. The listed languages are English, French, German, Italian, Japanese, Korean, Portuguese, and Spanish. Leopard supports Android, iOS, Linux, macOS, Windows, web, and Raspberry Pi, with SDK quick starts for several platforms, frameworks, and programming languages. Use requires a Picovoice AccessKey, which authenticates use and checks it against account limits. Usage is measured by audio processed per second and resets every 30 days. Leopard does not support real-time transcription. Pricing is on request; the 7-day trial costs nothing, includes all Picovoice products, requires no credit card, and does not auto-renew.
