This is one important tool for me as I could convert tons of sermons, lectures into text and even subtitle (with time stamps). Not only are they good for subtitles, but they are also go for searching keywords in speeches swiftly.
I have tested a few before so there are tons out there (Amazon Transcribe, Adobe Premiere, Otter.ai, etc.). So here I want to narrow the tools down.
I've just tested turboscribe.ai on Samuel Ling's Kant in Mandarin and it's not bad. Finding an accurate one for Mandarin/Chinese is not easy. Turboscribe claims to support around 100 languages.
