When thanking feedback providers, the context, format, and tone of your speech will affect your approach. For formal or professional speeches, you can thank them at the beginning or end of your speech by mentioning their names, roles, or organizations and summarizing their main points or contributions. You can also acknowledge their expertise, experience, or perspective and how it helped shape your speech. In an informal or personal speech, you can thank them more casually and spontaneously with humor, anecdotes, or compliments. You can also share how their feedback made you feel or inspired you, and invite them to continue the conversation or ask for more feedback in the future. For written or online speeches, you can thank them in a note, email, or social media post with emojis, gifs, or images to add some personality and emotion. You can link to their work, profile, or website and encourage them to follow up with you or check out your other speeches.
