I am going to cheat a little, my written Polish is extremely rusty and wasn’t that good in the first place.
I just tweeted a link to a Google translation so you might see some weird things in your stats.

I would have loved to have been in Warsaw, but I knew what I submitted in many ways was too early stage.

As far as the length of presentation, compared to some “contests” I believe Seedcamp is quite generous with the time. Plugg for instance the first presentation was just 2 or 3 minutes.
What would help the teams is watching lots of pitches from other events – Seedcamp, TC50, Plugg etc – and possibly read a few books from the likes of Guy Kawasaki – even his blog is a great source.

SkryBot is interesting – back in 1999-2000 when I was with Techland we already had English Translator on the market, but we were researching voice recognition with the likes of Dragon Naturally speaking.
From what I remember at that time an investment of around $2M was required for a language for licensing and building up a database.

There is increased risk in many ways looking to implement both the technology and data, unless they already have algorithms better than the competition.

Their competition also includes Google who have access to vast processing resources, and people providing data for free through Google Voice (though without text equivalent)
