FAQs

What is biometric anonymization?

Biometric anonymization removes or alters unique voice characteristics like timbre and pitch, transforming the voice into a new, natural-sounding one that cannot be linked to the original speaker. This ensures content usability while protecting the speaker's identity and privacy.

Does Nijta support real-time audio processing?

Nijta Version 4.0 supports faster-than-real-time audio processing but does not include native streaming capabilities. Users requiring streaming must implement their own streaming architecture, embedding API requests within their chosen workflow.

Can the age and gender of the speaker be preserved after anonymization?

Yes, the anonymized output allows explicit control over age group (young adult, middle-aged, senior, same, or random) and gender (same, opposite, specific, or random). This enables customization of the target voice identity.

What are the maximum audio file sizes for the API?

The maximum allowed size for audio files sent to the API is 10 MB. Files larger than this limit will be rejected by the system.

Does Nijta work for children's voices?

No, Nijta's current solution does not accurately work for children's voices. This is an active area of research, and Nijta is partnering with EdTech providers to develop a robust solution for this specific use case.
