Hi co-learner! I have finally found two online tools I can use in conjunction to compare any male or female voices (very good) with my own. I can paste any text in many languages and for free. There is a fee for larger use. I can even change the speech rate and and the voice shaping. Iit's really a must to perfect our pronunciation like a native!
Here are the links:
https://acapela-box.com/AcaBox/index.php
https://www.speakpipe.com/voice-recorder
Description of both services by the providers:
"The acapela-box service immediately converts any text into an audio file by using the high-quality text-to-speech voices by Acapela Group."
"SpeakPipe voice recorder allows you to create an audio recording directly from a browser by using your microphone. The recording is produced locally on your computer, and you can record as many times as you need. There is the option to save your recording on the SpeakPipe server and get a link to it, so you can send it via email or use on the web."
I hope this can be useful to you.
Feel free to share your experience here,
