AI voice agent costs slashed to 2.5¢/min via custom pipeline

By PulseAugur Editorial · [1 sources] ·

By migrating from a managed voice platform to a custom LiveKit pipeline, they reduced costs from approximately 10¢ per minute to 2.5¢ per minute. The largest cost component is text-to-speech (TTS), consuming nearly a cent per minute, while the LLM itself accounts for a minimal fraction of the cost.
