The characteristics that apply to the soliloquy speech form are:

1. Reveals a character's inner thoughts: This is true. A soliloquy is a device often used in drama when a character speaks to themselves, relating thoughts and feelings, thereby also sharing them with the audience, giving off the illusion of being a series of unspoken reflections.

2. Allow actors flexibility in interpretation: This is also true. Since a soliloquy is a monologue from a character's inner thoughts, it allows the actor to interpret and portray these thoughts in a way that best fits their understanding of the character.

3. Like the aside, is not heard by the other characters: This is true. Similar to an aside, a soliloquy is not meant to be heard by the other characters in the play. It's a way for a character to share their inner thoughts with the audience without the other characters knowing.

4. Usually spoken when others are on the stage: This is false. A soliloquy is typically delivered when the character is alone on stage, to emphasize the fact that they are sharing their private thoughts and feelings. However, there can be exceptions depending on the specific requirements of the play.
