f4x 2023 EngineBest recognition performance
c’t already certified 2021 “best detection performance in the test”.
(c´t 17/21). In October 2022, we completely renewed f4x and improved the recognition by about 50%. Good transcripts are now generated even from challenging shooting situations. This significantly reduces correction times.
Test f4x now with your data.
We give you 30 minutes contingent for new registration.
We maintain high safety standards GDPR compliant
We pay attention to high security standards and transparent infrastructure so that your data is processed by us in compliance with GDPR.
Your data will be used exclusively for speech recognition and not for other purposes or even passed on. The transmission of your data is already encrypted during the upload.
Read our f4x procedure concept (submitted to the Hessian Data Protection Commissioner) here.
Speech recognition runs exclusively on ISO-27001 certified servers in Germany.
Immediately after the conversion, the recordings are deleted. The text file is stored in encrypted form until collection. After that, the data is deleted from our servers. The finished transcripts are then only available locally to you as a text file.
By the way, our servers not only run securely, but 100% with climate-neutral energy from hydropower.
