delivery Factor

Speaker Tone

The overall emotional tone of the speaker throughout the video, analyzed from the transcript text. Captures how the politician sounds — not what they say, but how they say it.

Tone drives watch time. YouTube's algorithm heavily weights average view duration, and viewers abandon videos that feel monotonous or emotionally flat. Passionate and enthusiastic tones keep viewers engaged; neutral and calm tones risk losing them to more energetic content in their queue.

Each value below shows two numbers when available: Regular/Shorts is the effect on a typical video, and Top 10% is the effect on the videos that broke out (top decile of views). Use the Top 10% column to see what disproportionately helps videos that go big.

Indignant
