How they stack up
Choose between a voice creation workflow and AWS integration
ElevenLabs is worth evaluating when your team needs voice cloning and content creation tools. Polly is worth evaluating when speech generation needs to fit an existing AWS application or contact center.
- Check whether the desired voice is available in your language and model.
- Compare custom voice access, setup work, and commercial terms.
- Test the speech your users will hear, including names, numbers, and corrections.
Compare specific models, not provider labels
Flash v2.5 prioritizes low latency, Multilingual v2 targets consistent long-form speech, and Eleven v3 provides expressive generation. Polly's four engines also differ in voice selection, capabilities, and price. Calling all Polly voices robotic or treating every ElevenLabs model as equivalent misses those differences.
Polly's Generative engine supports bidirectional text and audio streaming. You can forward text as it arrives instead of waiting for a complete response. See the AWS streaming guide.
- Measure the first playable audio with the same transcript and network conditions.
- Listen for pronunciation errors and changes in delivery across longer passages.
- Repeat tests with the exact voice and settings you plan to use.
Compare the selected model and engine rates
ElevenAPI lists $0.05 per 1,000 characters for Flash/Turbo and v3 Conversational, and $0.10 per 1,000 for Eleven v3 and Multilingual v2. Subscription and pay-as-you-go options are available. Creative-plan allowances are a separate comparison, and introductory discounts are not the ongoing monthly price.
Polly lists $4 per million characters for Standard, $16 for Neural, $30 for Generative, and $100 for Long-form outside the free tier. Check the rate for your AWS Region. Estimate your bill with the engine you intend to deploy, then account for your expected usage. The ElevenLabs pricing page and Polly pricing page are the sources for current rates.
