Voice settings
Voice settings dramatically affect how your agent is perceived:
-
Stability: Lower values (0.30-0.50) create more emotional, dynamic delivery but may occasionally sound unstable. Higher values (0.60-0.85) produce more consistent but potentially monotonous output.
-
Similarity: Higher values will boost the overall clarity and consistency of the voice. Very high values may lead to sound distortions. Adjusting this value to find the right balance is recommended.
-
Speed: Most natural conversations occur at 0.9-1.1x speed. Depending on the voice, adjust slower for complex topics or faster for routine information.
Test your agent with different voice settings using the same prompt to find the optimal combination. Small adjustments can dramatically change the perceived personality of your agent.
