Phonetic Respelling for Lebedeva and Isinbayeva

[Percy Henry]

Can someone who speaks Russian tell me if the following phonetic respelling is a good anglicized approximation of the Russian Name Lebedeva?

/l y ey 1 b y ih d 0 y ax 0 v ax 0/

and Isinbayeva:

/ih 0 s y ih n 0 b aa 1 y ax 0 v ax 0/

Thanks
