I'd also suggest Duolingo which has audio for all sentences in its course and uses speech recognition.

Additionally the Pimsleur courses are great, with non-interactive lessons you can listen to with a media player. But relatively expensive, if you want to own it legally. They also don't do characters at all, so it can only be a part of the journey.

As an alternative to Pimsleur, you can often find a login to Mango Languages at your local library's digital resources, which uses a very similar teaching methodology.
