what do you guess of my age by voice?could i please chat with you?i am grateful for your tips
如果要用how old ,应该是 how old i am in your opinion by my voice 或者 how old you think i am
in your opinion 在你的观点里
grateful 是感谢,感恩的意思
chat with sb 与某人聊天
could i please相当于 can i ,但是could 更加委婉,表示请求。
以上是个人翻译,希望可以帮到你。
