Can we keep Google for other languages and use you for Thai?

Yes, and for many teams that is the sensible arrangement. Nothing in either API prevents routing by language.

Is there an OpenAI-compatible endpoint?

Yes. Point an existing OpenAI SDK at our base URL and call the speech endpoint; requests stream by default and bill at the same per-character rate.

Do you publish latency or quality numbers?

No. We publish no latency claims and no accuracy figures of our own, for our model or anyone else's. Test both on your own text.

How current are the prices here?

They come from each vendor's published list rate, recorded in one place and re-checked on a fixed schedule; the month of the last check is at the top of the page.

Do you run as a cloud TTS service?

Yes. The speech API is hosted and a request is one HTTPS call carrying an API key. Setup does not involve a cloud project or a service account.

Paxa Labs and Google Cloud Text-to-Speech for Thai

A Thai-first speech API next to a general cloud service, across language coverage, setup, billing, and the cases each one suits.

Start free See full pricing

Google Cloud Text-to-Speech is the default answer for a team that already runs on Google Cloud, and its language list is far longer than ours will ever be. The trade is the usual one with platform services. You get breadth, an existing billing relationship, and a service that will outlive most startups. You also get a service whose Thai is one entry among very many, and a setup path that begins with a cloud project. We are the opposite shape. One API key, one balance, and a model whose whole design constraint is Thai and English in the same sentence.

What differs

Dimension	Paxa Labs	Gemini 3.1 Flash TTS
Language coverage	Thai and English, treated as first languages. Nothing else.	A very wide list of languages and voices, documented on their site.
What it takes to start	Sign in, mint a key, send a request. No project, no cloud console, no card for the free credits.	A cloud project and its billing setup, as their own getting-started documentation describes.
Thai and English in one sentence	Paxa Flash handles the switch inside a single utterance, which is the case Thai product copy runs into constantly.	Their documentation is where to check how a mixed-language input behaves.
Regional Thai	Four regional voices read their own dialect lines, two Isan, one Northern, and one Southern.	Their Thai voice list is on their site.
What a failed request costs	Nothing. Credits are charged before inference and refunded automatically when generation fails.	Their billing terms are on their pricing page.

Paxa Flash, per 1M characters: $15
Gemini 3.1 Flash TTS: $42
Their rate, as a multiple: 2.8×

Both figures are published list rates per million characters, read from each vendor's own pricing page and re-checked on a fixed schedule.

What it costs at your volume

Speech, per month	Paxa Labs	Gemini 3.1 Flash TTS	Difference
100,000About 1.8 hours of speech	$1.50	$4.24	$2.74 less
1,000,000About 18 hours	$15	$42.40	$27.40 less
5,000,000About 92 hours	$75	$212	$137 less
20,000,000About 370 hours	$300	$848	$548 less

Every figure is the two published rates multiplied by the volume beside it. Where the other vendor publishes a range, the low end is compared and the range is shown.

When Google Cloud is the better choice

If you are already on Google Cloud, the marginal cost of turning on one more service there is close to zero, and that matters more than a rate card. If you need dozens of languages, the comparison is not close. If your procurement requires a vendor with global compliance certifications and a support contract, a cloud provider clears a bar we do not yet clear. Weigh us when Thai is the whole workload, and when a smaller, faster-moving vendor is an acceptable trade for a model built around your language.
