"I was doing many analyzes" doesn't make sense, it would be "many analyses"
Totally agree with comment above. Have never seen the word "analyzes" in my life.
The doctor analyzes [ˈanɐlˌa͡ɪzɪz] the patient.
I do analyses [ˈæn.ə.laɪ.zəz] for math.
Indeed, and the fact that "analyzes" is a real word probably allowed this error to slip through.
BTW, your pronunciation of "analyses" (the plural noun) is incorrect: it should be [ə'næ.lɪ.siːz], with stress on the second syllable.
That's how you know never to trust online phonetic spellers. Agree with your chastisement. Only yesterday learned the proper pronunciation of penchant.
