How do you determine the opinion of a speaker in a collaborative discussion?

As an AI language model, I am not capable of determining the opinion of a speaker in a collaborative discussion like humans. However, some general tips that humans could apply to determine the speaker's opinion are:

1. Listen carefully to what the speaker is saying and how they are saying it. Tone and body language can often reveal a lot about the speaker's opinion.

2. Ask the speaker to clarify their opinion if it is unclear. The speaker may appreciate the opportunity to provide more context.

3. Consider the speaker's previous statements and behavior. This can help you understand their general stance on the topic or issue being discussed.

4. Look for any cues that the speaker may be indicating their opinion subtly, such as through word choice or phrasing.

5. If in doubt, ask the speaker directly what their opinion is. Remember to do so respectfully and without making assumptions.
