Youtube is far from the best speech-to-text technology available. The best STT technology is probably owned by the NSA or companies that work with them. Part of the secret sauce to good STT is voice training and speaker recognition, which I don't believe youtube's STT is capable of yet. As far as Youtube is concerned, it's only one person talking throughout each video, so when you have a French dude speaking one sentence, followed by an Irish woman the next sentence, youtube may not dynamically adapt to that.
But besides that, the first thing any STT vendors ask when you start talking to them is about the quality of the recorded sound. If your speakers are not in a low-noise environment with good microphone setups, the results will always be disappointing.
