I'm using Siri a lot and loving it to the point where I prefer to dictate emails on my iPhone than write them on my MacBook. I've learnt quite a few special commands, such as 'cap', 'new paragraph', 'Euro sign', etc. and I'm teaching myself the skill of dictating and trying always to remember to say 'comma' or 'full stop', etc. Does anyone know a site that has a comprehensive glossary of the special commands? I've been trying to dictate a space character but I haven't found out how to do it, if it's possible. I just discovered that if you say 'zero' you get 'zero', but if you say 'zero one two' you get '012'! I must update my signature, as I now have an iPhone 4s.
