Who Google Cloud Text-to-Speech suits

We file Google Cloud Text-to-Speech under cloud provider speech services: speech is one product among many in a larger cloud account, with its own console, billing and permissions. It lists a price per character. The audience its pages name: teams already on Google Cloud, or teams that need broad language and voice coverage, with Standard and WaveNet voices at $4 per 1M characters and optional Chirp 3 HD voices.

Check the difference between voice classes, whether the free allowance renews monthly or runs out once, and what the account minimums and regional prices are.

Google Cloud Text-to-Speech's Standard voices at $4 and WaveNet voices at $4 match ReadAloud Live at $4 per 1M characters.

Google Cloud Text-to-Speech's Neural2 voices at $16, Polyglot (Preview) voices at $16, Studio voices at $160, Chirp 3: HD voices at $30 and Chirp 3: Instant custom voice at $60 are higher than ReadAloud Live.

Google Cloud Text-to-Speech's Standard voices at $4 and WaveNet voices at $4 are lower than ReadAloud Studio at $10 per 1M characters, so on list price per character Google Cloud Text-to-Speech costs less there.

Google Cloud Text-to-Speech's Neural2 voices at $16, Polyglot (Preview) voices at $16, Studio voices at $160, Chirp 3: HD voices at $30 and Chirp 3: Instant custom voice at $60 are higher than ReadAloud Studio.

Account, compliance and data handling

We did not find HIPAA, SOC 2 or GDPR wording on Google Cloud Text-to-Speech's pages. No product-specific compliance statements found on the Text-to-Speech pages read; Google Cloud publishes compliance information at the platform level that was not reviewed here. ReadAloud does not claim HIPAA, SOC 2, GDPR or other certifications. If you need one of them, ask the vendors you are considering what they can show you.

Limits and formats

  • Per request: 5,000 bytes per request (multi-byte characters such as ja-JP use more than one byte). (source: cloud.google.com)
  • Concurrency: Quotas per project: 100 concurrent streaming sessions; 200 requests per minute for Chirp 3; 500 for Studio; 1,000 for Neural2, Polyglot and default voices; 30 per minute for Chirp voice cloning. Gemini-TTS 2.5: 150 (Flash) and 125 (Pro) queries per minute. Limits subject to change. (source: cloud.google.com)

What we could not confirm about Google Cloud Text-to-Speech

  • All Google prices are single-source (the pricing page); no second Google page repeated the numbers
  • WaveNet is listed at $4 per 1M characters with the same SKU id as Standard; this may be a pricing-page quirk, and we did not check the pricing calculator
  • Whether streaming is WebSocket or HTTP (bidirectional streaming doc is a Preview; transport not confirmed)
  • Vendor-stated latency figures (none with numbers found)
  • Access requirements for Instant Custom Voice
  • Compliance statements (HIPAA, SOC 2, GDPR) for this product
  • Client library languages
  • OpenAI-compatible mode (none found)

What to consider when choosing a Google Cloud Text-to-Speech alternative

  • Price your monthly characters on each Google Cloud Text-to-Speech tier you would use.
  • Decide whether you need audio to start before the whole text is sent. If you do, check that the service you pick streams input as well as output.
  • Google Cloud Text-to-Speech's per-request limit is stated as: 5,000 bytes per request (multi-byte characters such as ja-JP use more than one byte). Compare it with the length of your longest text and plan how you will split it. (source: cloud.google.com)
  • If you rely on SSML for pauses or pronunciation, note that Google Cloud Text-to-Speech lists support for it and that ReadAloud does not accept SSML.
