Frequently asked questions
Functionality
What is biometric anonymisation ?
Biometric anonymisation is the process of removing or altering the unique voice characteristics that can identify a person — such as vocal timbre, pitch patterns, rhythm, and other biometric markers. Instead of masking or distorting the audio, the voice is transformed into a new, natural-sounding voice that cannot be linked back to the original speaker.
This ensures that the content of the speech remains fully usable while the identity, privacy, and safety of the speaker are completely protected, meeting strict standards like non-linkability, non-singling-out, and non-inference.
How many languages do you support ?
Our solution currently supports English, French, German, Spanish and Italian. If you cannot find your preferred language in the list, please reach out to us - we can add a new language in just one day!
What file formats do you support ?
We support all the popular audio formats. Please refer to our documentation for a list of supported formats.
Does it work in real-time, for example, streaming audio ?
For now, our solutions do not work in real-time. We plan to release the real-time version of our solution by Q3 2025.
Does the anonymisation work for children's voices ?
No, our solution does not accurately work for children's voices. This is an active area of research at Nijta and we are partnering up with renowned EdTech providers to build a robust solution for children’s voices.
Could the age and gender of the speaker be preserved after anonymisation ?
The gender of the output voices can be controlled, but not the age. We are working actively to provide the age preservation feature.
Could the original emotion of the speaker be preserved after anonymisation ?
We have observed that the original emotion is degraded after anonymisation, but it could be retrieved by fine-tuning the emotion detection model using anonymised voices. We are working on an anonymization technique that will preserve the original emotion with high-fidelity.
Could the non-verbal cues such as the speaking pace, pronunciation, intonation, etc. of the original speaker be preserved after anonymisation ?
Yes, such non-verbal cues are largely preserved under certain conditions. We sometimes notice small degradation in the pronunciation.
Do the speech biomarkers related to the health attributes of the original speaker be preserved after anonymisation ?
We cannot say that with certainty. We are currently working on R&D projects to preserve the speech biomarkers.
Can the anonymisation filter profane language ?
This is an active area of research. We are working with a large group to filter profane language in live calls.
Performance
What is the accuracy of your solution ?
We have observed significant improvements in privacy benchmarks after anonymisation. The probability of singling out and linkability which refer to the legal guarantees of anonymisation are improved x% and y% relative to unprotected audio. The error rate of PII redaction is less than 1%.
What is the processing time of your solution ?
- We have evaluated the speed, reliability, scalability, and efficiency of our system on this config: 15 cores, 45 GB RAM, 1 x Tesla V100S.
- We were able to anonymize 1 hour in 4 min with 1 worker processing batches of 30 files (voice only).
What is the maximum size of audio files that could be sent to the API ?
Audio files should not exceed 500 MB in size. The API will not accept files larger than this limit.
How many concurrent requests could be processed by the API without degrading the processing time ?
The system supports concurrent requests, allowing a maximum of 10 simultaneous requests per user.
Can the customer fine-tune the models hosted on their site ?
No, we do not offer fine-tuning service of our models on customer’s site.
Installation
Does it work as a SaaS or on-premise ?
We provide both SaaS and on-premise solutions.
What are the computational requirements for hosting the on-premise solution ?
- Operating system : Linux (Ubuntu 20.04 or later)
- Processor : Intel Xeon Gold 6226R or later
- RAM : 32 GB minimum
- Disk space : 100 GB minimum
- GPU : Nvidia Tesla V100S - 32 GB minimum
What are the concrete measures followed to ensure the security of the SaaS solution ?
We follow SOC2 compliance measures to ensure the security of our hosted SaaS solution. Please refer to our documentation for more information.
