LMNT

Former speech provider behind Aurora and Blizzard, plus managed voice enrollment and conversion workflows. Provider has shut down; entries preserve historical contracts and original branding.

Two named native speech families and three explicitly managed historical offerings. Original/private checkpoints and enterprise-preview inventory remain incomplete. Public DiffWave and WaveGrad research weights excluded.

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.
