The short version

  • Only Amazon Translate has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon Translate the generous 2 million character monthly free tier applies only for a customer’s first 12 months on AWS, so translation costs step up materially in year two with no change in usage.; Sonix monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.
  • They diverge on capability: Amazon Translate covers Text translation API, Sonix covers Automated transcription.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Amazon Translate

  • The generous 2 million character monthly free tier applies only for a customer’s first 12 months on AWS, so translation costs step up materially in year two with no change in usage.
  • There is no consumer-facing app or website, so it is unusable for casual personal translation the way Google Translate or Microsoft Translator are.
  • Document translation of Office files costs double the standard per-character rate, which is easy to underestimate when budgeting a document-heavy project.
  • Active Custom Translation, the tool for improving output with domain-specific data, costs four times the standard rate at $60 per million characters.
  • As with all major MT APIs, output for low-resource languages and specialised terminology often still needs human review, so it does not substitute for a human translation service on customer-facing or legally sensitive content.

Sonix

  • Monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.
  • Unused hours do not accumulate into a meaningful reserve, so an irregular workload of a heavy month followed by a quiet one pays overage in the first and wastes allowance in the second.
  • There is no human correction tier at self-service prices, so anyone with an accessibility or legal accuracy obligation has to add a separate supplier or a member of staff to the workflow.
  • The cited 99 percent accuracy is a best-case figure on clean single-speaker audio, and overlapping speakers, strong accents, technical vocabulary and room noise degrade it enough that editing time, not transcription cost, becomes the real expense.
  • Storage is capped per plan at 25GB to 100GB, and video files consume it fast, so long-running teams end up deleting source media or upgrading a tier for storage they do not otherwise need.

Answered from the vendors’ own pages

Amazon Translate: How generous is the free tier really?

2 million characters per month, the largest of the three major cloud APIs, but only for the first 12 months after which standard per-character pricing applies to everything.

Sonix: What does Sonix cost per hour?

$10 an hour on pay-as-you-go, and $10 an hour for any usage beyond the monthly allowance on every subscription tier. That overage rate is published, which is unusual in this market.

Amazon Translate: Is there a consumer app like Google Translate?

No, Amazon Translate is a developer API only, accessed through the AWS console and SDKs, with no separate public-facing app.

Sonix: Is there human transcription?

No. Sonix is automated transcription plus an editor for you to correct. If you need a contracted accuracy level, this is the wrong category of product.

Amazon Translate: How much does document translation cost compared to text?

Double the standard rate, at $30 per million characters for Office file formats.

Sonix: How accurate is it really?

The 99 percent claim assumes clean, single-speaker, standard-accent audio. Multi-speaker recordings with background noise land noticeably lower, and the cost shows up as your editing time.

Sonix: How many languages?

Transcription in over fifty languages and translation into a similar number, which is wider than most self-service competitors.
