I refuse to talk in terms of 'sounds like', because any such answer would only be accurate if I can assume you pronouce the words properly; and in any case, the same answer might be read by someone else who doesn't; and word breaks (as between 'hyou' and 'go') are another area for misunderstandings). Besides, 'hy-' is very rare at the beginning of an English word - so again I would be guessing at what sound you are trying to represent; 'hy-' normally represents the syllable /haɪ/, as in 'hydrant' or 'hydrogen'. For all I know, your 'hyou' might represent /'haɪju:/ I know not everyone is comfortable with the IPA. Tough - it's a great tool.
I think he's saying /'hju:gəʊ/ - it's hard to tell in such a short clip. (There is the complication that - I think - the brand is French - but he's certainly not saying [yg'ɔ] (as a French speaker would).
