Strengths and Limitations

Strengths

  • Exceptional Stability: Very consistent output across generations.
  • Clean, Studio-Like Sound: Minimal artifacts, noise, or glitches.
  • Predictable Delivery: Ideal for workflows that value reliability over expressiveness.

Limitations

  • Monotone Tendency: Can sound emotionally flat or lifeless in expressive or character-driven scripts.
  • Limited Emotional Range: Emotions are preset and subtle compared to more performative models.
  • No Audio Tags: Does not support bracket-based or expressive tags.

Tips for Better Prompts

  • Write Clean, Neutral Scripts: The model performs best with clear, direct language rather than theatrical dialogue.
  • Use Punctuation for Rhythm: Commas, periods, exclamation marks, and parentheses can be used to direct and guide natural, more expressive pacing. 
    • For example, for a more dramatic effect, the phrase:
      •  “Listen, If we walk away today, me, you, all of us, we may never get another chance.”
    • Can be written: 
      •  “Listen… If we walk away today? me… you… all of us: we may never! get another chance...”
  • Add context: If optional for your workflow, add context to the prompt, and later cut it out using an editing software. For example, instead of “This is how you do it.”, write “And then the smug man softly said: “This is how you do it.””
  • Spell out numbers and dates: instead of “Using Minimax 2.0 is great”, type out “Using Minimax two point oh is great.
  • Leverage Speed Control: Slight speed adjustments can dramatically improve delivered performance.
  • Insert Pauses Intentionally: Use “<#1.0#>” to add pauses to create emphasis or breathing room. For a two-second pause, for example, add “<#2.0#>”
  • Avoid Over-Directing Emotion: Let the model stay within its strength zone - subtle emotional cues work better than dramatic ones.
