Yes! Let me if you need any assistance, or if you could use help you host the conference calls. (I often run meetings in the workplace, and use my "presentation voice" to speak more clearly.) Another idea - many people stutter on their names, hometowns, or other (unavoidable) proper nouns. How about a (short) written bio? That way, attendees can introduce themselves if they're comfortable. (Or have the host read it.) Alternatively, we can let people skip an intro and go directly into speaking about their topic.
