Chime in means joining a conversation already in progress with a comment. Speak up means becoming audible or assertive, or raising an issue despite reluctance to do so -- the focus is on being heard or overcoming hesitation, not on timing your entry.
Different questions, not different degrees
These two verbs answer different questions. "Chime in" is about when and how you enter a flowing exchange. "Speak up" is about volume, visibility, or courage -- it's the right word when someone is too quiet to be heard, or hesitant to raise something uncomfortable, regardless of whether the conversation is actively flowing.
"You've been quiet on this call -- please speak up if you disagree with the plan." -- about audibility and reluctance, not timing.
"Feel free to chime in on the parking question before we wrap up." -- a routine, low-stakes conversational entry.
A quiet colleague at the back of a call who has a concern needs to "speak up"; a colleague already in the mix of a discussion who wants to add one more point can simply "chime in."
Telling a hesitant colleague to "chime in" about a serious concern undersells the courage the moment actually requires:
Wrong fit: telling a hesitant colleague to "chime in" about a serious concern undersells what it takes -- "speak up" names that more accurately.

The useful test is asking what's actually stopping the person: is it that they haven't found the right moment to enter (chime in), or that they're quiet, unheard, or reluctant to raise something at all (speak up)? Those are two different problems, and only one of them is solved by simply finding a pause in the conversation.
The mistake: treating the two as interchangeable
The mistake is treating the two as interchangeable participation words. "Chime in" addresses timing and entry into a live exchange; "speak up" addresses whether someone is being heard or is willing to raise something despite hesitation.
Practice scenarios
Practice using chime in in situations like:
- telling the difference between a timing problem and an audibility problem
- encouraging a quiet colleague with the right word for the actual barrier
- choosing chime in for a routine, low-stakes conversational entry
Useful practice phrases:
- "Please speak up if you disagree."
- "Feel free to chime in before we wrap up."
- "I want to hear from everyone -- please speak up if something's on your mind."
"Chime in" asks when.
"Speak up" asks whether you'll be heard at all.
Naming the actual barrier is what gets someone the right encouragement.
