I found a good video in Easy Russian channel, “How to improve your pronounciation“. In that video, Maria showed how she improves her English speaking by recording her speech then listening to it.
I’ve ever done that with my English. I recorded myself speaking English then I listened to my voice and I found it terrible. It was fun anyway. I guess I will record myself speaking Russian after this.
You should try that, too. Record yourself speaking foreign language then listen. If it doesn’t sound good, try again.
