M. Colmar parle au téléphone son retour chez lui.

Mr. Colmar speaks on the phone when he returns home.

Explanation:

Speech: Speech is human vocal communication using language. Each language uses phonetic combinations of vowel and consonant sounds that form the sound of its words, and using those words in their semantic form.

Phone: A mobile phone, cellular phone, cell phone, cellphone, handphone, or hand phone, sometimes shortened to simply mobile, cell or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area.

Mr: Mister, usually written in its abbreviated form Mr. (US) or Mr (UK), is a commonly used English honorific for men under the rank of knighthood. The title 'Mr' derived from earlier forms of master, as the equivalent female titles Mrs, Miss, and Ms all derived from earlier forms of mistress.

Home: the place where one lives permanently, especially as a member of a family or household.

Hope this helps!
