Final answer:
Four items essential for developing an effective command voice are voice control, non-verbal communication like gestures and posture, cultural awareness, and the use of specific terms or jargon with clear enunciation and respectful language. Crafting messages that are authentic and relatable and ensuring technical elements are well tested also contribute to speech delivery effectiveness.
Step-by-step explanation:
In order to develop an effective command voice, there are several elements that are essential. First and foremost, voice control is crucial. This includes the ability to modulate volume, tone, and pace to suit the message and the audience. Secondly, non-verbal elements such as gestures and posture play a significant role in reinforcing the spoken word and conveying confidence and authority.
Thirdly, an effective communicator must also be aware of and apply cultural considerations. This involves understanding and respecting diverse backgrounds and customs, which can greatly influence how a message is received. Lastly, the use of specific terms or jargon, clear enunciation, and respectful language ensures that the communication is professional and accessible to the audience.
In addition to these elements, crafting messages with careful sentence structure and word choices can enhance the effectiveness of a command voice. An authentic voice that reflects the speaker's true personality and connects with the audience is also vital. The use of technology in presentations should engage the audience and be well tested to avoid technical difficulties. Overall, these components come together to create a command voice that is authoritative, credible, and capable of making a strong impact.
