WellSaid

Proprietary voice synthesis with Caruso delivery controls, a Legacy engine and a hosted catalog that includes partner voices.

Two documented voice model selectors, three generation transports per selector, and the published voice compatibility directory. Immutable revisions and numerical API tariffs remain unresolved.

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.
