How To Use This

• Read each tag list from left to right.
• Left side means more balanced, subtle, or restrained.
• Right side means more extreme, forceful, or obvious.
• If you want the strongest controllable result, start from the rightmost tag.
• If you want a more natural or less exaggerated result, move one or two steps left.

​

​

Practical Rule Of Thumb

• Use the leftmost tag when you want the emotion to be present but not overpower the sentence.
• Use the middle tags when you want clear emotional color without sounding theatrical.
• Use the rightmost tag when you need the emotion to come through strongly and consistently.

• Nervousness, subtle: [uneasy]
• Nervousness, clear: [anxious]
• Nervousness, strongest: [trembling]

​

How To Generalize This To New Emotions

• Start with 3 to 4 tags for the same emotional family.
• Arrange them from balanced to extreme.
• Test them on the same sentence.
• Keep the tag that gives the clearest emotional control without distorting the sentence too much.
• When in doubt, the most extreme tag often gives the strongest controllability.

Combining Tags

response = client.text_to_speech.tts(
    text="[sighing, secretive] I have a secret to tell you... [happy, excited] We're going to Paris!",
    voice_id=147320,
    language="en-us",
    speech_model="mars-instruct",
    output_configuration=StreamTtsOutputConfiguration(format="wav")
)

Pauses

You... must... understand... this. <break time='600ms'/> The future begins NOW.

​

Best Practices

1. Use specific tags - Place concise delivery tags near the sentence they should affect
2. Match content to emotion - Text and punctuation should reflect the emotional tone
3. Place sound effects naturally - Tags like [laughing], [sighing] work best within sentences
4. Keep tags short - Tags like [happy], [sad], or [whispering] work best when focused
5. Add pauses - Use <break time='600ms'/> for dramatic effect
