Alex Morse is a verb? This appears to be a name rather than a standard verb. If used as a verb (e.g., to alex morse something), it would be nonstandard. Typically, the phrase refers to a proper noun (two-word name) pronounced as /ˈæ.lɛks ˈmɔːrs/ in US English, with stress on the first syllable of each word and non-syllabic liaison between words. For clarity, treat it as a proper noun pronounced as two distinct names rather than a conventional verb.
