-        Generate a short, natural-sounding English sentence (10–20 words) that a person could say aloud 
-        to clearly state their informed consent to use their voice for generating synthetic audio with 
-        an AI model called {audio_model_name}.
-
-        The sentence should:
-        - Sound natural and conversational, not like legal text.
-        - Explicitly include a consent phrase, such as “I give my consent,” “I agree,” or “I allow.”
-        - Mention the model name ({audio_model_name}) clearly in the sentence.
-        - Include a neutral descriptive clause before or after the consent phrase to add phonetic variety 
-        (e.g., “The weather today is bright and calm” or “This recording is made clearly and freely.”)
-        - Have a neutral or polite tone (no emotional extremes).
-        - Be comfortable to read aloud and phonetically rich, covering diverse vowels and consonants naturally.
-        - Be self-contained, so the full sentence can serve as an independent audio clip.
-
-        Examples of structure to follow:
-        - “The weather is clear and warm today. I give my consent to use my voice for generating audio with the model {audio_model_name}.”
-        - “I give my consent to use my voice for generating audio with the model {audio_model_name}. This statement is made freely and clearly.”
-        - “Good afternoon. I agree to the use of my recorded voice for audio generation with the model {audio_model_name}.”
-
-        The output should be one to three natural sentences ready to be spoken aloud for recording purposes. 
-        Only output the sentences that the speaker should read, no extra information, no justifications, no formatting or lists. Only the suggested sentence.

+        Generate exactly two short, natural-sounding English sentences (10-15 words each) that a person could say aloud, using everyday language.
+
+        Sentence 1 (Consent sentence):
+        * Clearly states informed consent to use their voice for generating synthetic audio with an AI model called {audio_model_name}.
+        * Must explicitly include a consent phrase such as “I give my consent,” “I agree,” or “I allow.”
+        * Must clearly mention the model name {audio_model_name} in the sentence.
+        * Should sound fluent, polite, and natural to read aloud.
+        * Should have a neutral or positive tone and be self-contained.
+
+        Sentence 2 (Phonetic variety sentence):
+        * Should not repeat the consent content.
+        * Adds phonetic variety with a neutral descriptive clause, for example about {topic}.
+        * Should be fluent, natural, and comfortable to read aloud.
+        * Should sound polite and neutral, without emotional extremes.
+        * Should include diverse vowels and consonants naturally for clear pronunciation.
+
+        FORMAT:
+        * Output EXACTLY two sentences.
+        * No numbering, no quotes, no bullet points, and no introductory text.
+        * Use standard punctuation.
+
+        Example format (don’t copy text, just the format):
+        I give my consent to use my voice for generating audio with the model {audio_model_name}. The weather is clear and calm this afternoon, and I’m speaking at an even pace.
