ReadSpeaker

Proprietary neural voice families, licensed local speech packages, hosted speech and custom voice development, including ReadSpeaker Korea. Some hosted voice choices use third-party engines.

Three named neural families plus five explicitly managed speech/custom/recognition offerings. Regional version mappings, historical families and account-specific contracts remain incomplete.

What does one question cost?

Compare every model with the same request.

Input tokensOutput tokens

Estimate = (input tokens × input price + output tokens × output price) / 1,000,000. Include conversation history in input and billed reasoning in output. Input-only decision models ignore the output setting; enter all billed input for one decision, including its question and criteria. Media, tools and discounts are separate.
