Chirp 3: HD voices, from Google, is purchasable on the one route we track. 1M characters of speech costs $30.00 at Google Cloud, the cheapest published rate we can cite. This model is billed at 1M characters / speech, which nothing else on the index sells, so its price is not ranked against the other models.
Every price on this page buys 1M characters of speech. Figures come from each seller's own published rates and carry the date we last read them.
Which route should you take
Each row is the table above read for one question, at the unit named beside the price. Rows marked our call are editorial judgement instead, and appear only where we have something specific to say.
Every price here buys the same thing: 1M characters of speech. That is a baseline for comparing providers, not a quote. What you are actually billed depends on the settings you send, and on some routes on how much you top up at once. Every figure is the provider's own published price; anything we derived rather than read off a price list is marked est.
Things that change what you pay without changing a price on this board. None of them is applied to the figures above: what one unit costs at the posted rate is a number anyone can check, and what it costs after a bonus depends on how much you buy at once.
Google Cloud · term
The first million characters each month are free. The rate here applies after that allowance, so a small workload pays nothing and this figure is what the next million costs. cloud.google.com
How these prices were read
How each figure above was read off the provider's own price list, and what that price list does not say.
Google Cloud
Google prices this per character and states the bulk rate itself. A single character costs thirty nanodollars, which is finer than this site can store as a price, so the figure here is the rate for a million characters, exactly as Google publishes it.

Where a row says not verified, we have not checked that figure yet; it does not mean the model lacks the feature. Every row is read off published documentation for the model, never from our own testing.
