The trombone is prettay prettay good at mimicking human conversation.
The first example that comes to my mind is the abstraction of adult voices in those old Peanuts cartoons:
One of the more noteworthy implementations of this idea of in Robert Erickson's General Speech. Commissioned by the great Stuart Dempster, the work is essentially a transcription of the "Duty, Honor, Country" speech given by General MacCarther at West Point Military Academy in the 60's. The piece requires the trombonist to speak through the instrument and employs a number of theatrical elements.
Here is an excellent and thorough realization of the piece by Obie Berk Schneider, complete with supertitles!
Recently, I had the distinct honor to premiere a new solo work by Hilda Paredes, entitled Parafrasis. I've been a fan of her work for some time, so it was very exciting for me to play this new piece.
According to Hilda, Parafrasis is "a paraphrase of the speech of a character in
my opera el Palacio Imaginado. The first scene is an inauguration of a summer palace by the dictator of a country in Latin America and he gives a speech.

It is not so important to understand the actual meaning of the original source, as the piece is more about the ego and neurosis of the character, bordering into the ridiculous."
