Idapted, a San Jose start-up that offers a Web-based tutoring platform teach English to Chinese, has raised an undisclosed amount of cash from Ambient Sound Investment and the Sacramento Angels.

Alarmclock first reported the investment last week.

Ambient Sound Investment is the Estonian-based investment firm of four early Skype engineering employees.

The company says it focuses on teaching common conversations and everyday spoken language aspects rather than taking classroom studies and converting them to the Internet.

The service will go live this year.
