Final answer:
Voice telephony facilitates bi-directional voice communication, which has been enhanced by technological advancements such as microwave and satellite transmission. These improvements have led to more options for consumers and better service. The importance of vocal delivery in communication, including tone and pitch, also plays a critical role in effective telephony.
Step-by-step explanation:
Voice telephony is an efficient means of bi-directional voice communication with machines that can listen. This means users can have a two-way conversation with another person or an interactive system that responds to voice input. Improvements in technology, such as phone calls made via microwave transmission, communications satellites, and other wireless technologies, have enhanced the quality and reduced the costs of phone calls, leading to more consumer choice and better-quality service. Moreover, the evolution of mobile phones has necessitated new norms and behaviors due to the public presence of phone conversations, leading to alternatives like texting for quiet communication.
Whether using old or new methods of communication, it's not just the words but also the voice and tone that establish a connection with the audience. These are crucial in creating engagement and helping with comprehension. Vocal delivery includes the tone, pitch, and rate of speech.
