Key Differences

Um is often used to signify a brief pause during speech, indicating the speaker is thinking or unsure. Whereas Umm, with an extra "m," implies a longer pause or a greater level of hesitation. This distinction subtly affects how the speaker's uncertainty or thoughtfulness is perceived by the listener.
Um can serve as a linguistic filler in conversation, helping to maintain the flow while the speaker gathers thoughts. On the other hand, Umm may be employed not just for thought collection but also to signal a more significant interruption in the speaker's train of thought, possibly because the speaker is considering multiple ideas or is more deeply unsure.
In formal speech or presentations, "um" might be used sparingly to avoid disrupting the flow of information. Conversely, "umm" tends to be less common in formal settings, as it suggests a more pronounced pause which can detract from the speaker's perceived preparedness or confidence.
In text, "um" can convey a momentary hesitation or a conversational tone, making dialogue appear more realistic. Whereas "umm" in written form often emphasizes a more noticeable pause or uncertainty, potentially adding dramatic effect or indicating deeper contemplation.
The frequency and context of "um" versus "umm" usage can also reflect cultural communication styles, where "um" might be more prevalent in fast-paced conversations. In contrast, "umm" could be more common in contexts where taking time to formulate responses is valued.
