Thank you both very much!
Seraph:
Thank you! That phrase was supposed to be "deadly dull".
Hanna:
Thank you for such an awesome answer. And particularly for notices about TH's, accent and your kind words.
Though I hear that I mispronounce some sounds/words and I guess it means nothing yet but there's a lot of work ahead.
I just finished (I hope so) learning sounds themselves and I don't practice fluency yet. That was my challenge, actually. And that said, Seraph's remark makes me thinking I didn't get all of them right (because a native speaker can't understand my speech properly), so I have to brush them up, certainly.
I'm interested mostly now in clear enunciation of the sounds rather than in fluency, so I expect advices like "You failed with the [or] in the [short] and with the [a] in [about]. Make it more softer.... etc ". Like that. I will keep the topic up, and will be very grateful to anyone native speaker who would help me to improve my pronunciation with any advice or by any other means.
Thanks again![]()
