Which communication method involves only fingerspelling and speech sounds?

The Rochester Method is a communication technique that utilizes fingerspelling combined with speech. In this method, the manual alphabet is used to spell out words while simultaneously producing spoken sounds. This approach is particularly beneficial for individuals with hearing impairments, as it provides a clear means of conveying words visually through fingerspelling while maintaining the auditory aspect of speech.

In contrast, American Sign Language (ASL) is a complete language with its own grammar and syntax, which includes signs that represent concepts rather than spelling out individual words. Signed Exact English is another method that aims to represent English grammar and vocabulary systematically using signs, but it is not limited to fingerspelling and speech sounds. Visual-Gestural Communication encompasses a wide range of gestures to convey meaning without adhering strictly to any language structure, further differentiating it from the Rochester Method.
