Speech to text software (audio transcribing) for mac [closed]

What is the best speech to text software for mac? I have an hours worth of audio that I need to transcribe, and I'd really like to not have to do it manually :-).

I prefer free options and I like open source so if there is a project I'd like to know. All answers are welcome though.

Tough domain. There's no open source projects, that I'm aware of. Speech to text is probably best classified as a open research problem still. If you're prepared to punt $200, there's MacSpeech Dictate. But I'd be wary of claims of 90% accuracy.

Worth noting the case of SpinVox, a company that claimed to translate Voice Mail into text messages automatically, but had to use call centres full of workers in South Africa and the Philippines to do so accurately.

One thing you could try (although not on a daily basis) is uploading the audio as a video to Youtube, then asking YouTube to transcribe the video, giving you English captions...can take up to 24 hours for YouTube to do this, however...The caption file is even downloadable and you can edit them yourself, so you could copy and paste the text to wherever you wanted...

Found VoiceBase to be the best free transcribing tool and it is online so you don't need to install any software and works everywhere. I use to record voice memos in my iPhone and send them there.

Files of around 5MB/7 minutes (500-600 words) take 5-10 minutes to get transcribed (they send you an email when finished). It is sometimes inaccurate (ie. transcribes bias instead of buyers) and doesn't do any punctuation but I'd say 80-90% of the transcription is correct. It definitely saves a lot of time and keystrokes.
