+- play the isolated words in the recordings, to compare the 'ideal' pronunciation with the learner pronunciation (now it's possible on the old frontend, complicated to implement with Gradio - waiting for [this](https://github.com/gradio-app/gradio/issues/9823))
+- added also a Text-to-Speech in-browser (it works only if there are installed the required language packages. In case of failures there is the backend Text-to-Speech feature)
 
 ### TODO
 
-- save the synthetic audio speech from the text-to-speech voice as an audio file to play within the Gradio audio component
-- play the isolated words in the recordings, to compare the 'ideal' pronunciation with the learner pronunciation (now it's possible on the old frontend, complicated to implement with Gradio - waiting for [this](https://github.com/gradio-app/gradio/issues/9823))
 - improve documentation (especially function docstrings), backend tests
 - move from pytorch to onnxruntime (if possible)
 - add more e2e tests with playwright
