Voice and audio: the cheapest models
Speech to text, text to speech and phone agents.
How this page ranks
- Ranked by blended price per million tokens: three parts input to one part output, at the OpenRouter list price for the model. Lowest first. Ties go to the lower input price.
- A model counts for this job when its taxonomy v2 classification names voice and audio, or its old category maps to it.
- Each model must list audio input or output on OpenRouter or on its own record.
- Prices and scores come from the market tables only, each with the day it is for. The price on a model's own record is not used.
- Missing data never ranks. A model with no confirmed price in the last 30 days, a price in another unit, a $0 listing or unknown inputs and outputs is listed apart, with the reason.
Market data as of 10 Nov 2026. Prices: OpenRouter models API (official).
