Latency

Natural human conversations occur at around 200 milliseconds latency. For genuinely immersive, real-time conversational interactions, AI speech must fall below this threshold.

Latency comparison - Model time (excl. Network Latency)

• ElevenLabs: 75ms
• Amazon Polly: 200ms

ElevenLabs maintains a faster, more consistently low-latency experience essential for real-time applications.

Expressiveness

ElevenLabs is contextually aware and gives you full control

ElevenLabs uniquely provides contextual control, meaning fewer manual adjustments yield superior, naturally expressive results. While other platforms like Amazon Polly offer basic adjustments, ElevenLabs delivers consistently high-quality, contextually nuanced speech output, including speed adjustments.

Voice selection

ElevenLabs has 1,000s of human-like voices

ElevenLabs offers an extensive voice library featuring over 5,000 AI-generated voices, plus advanced tools like Voice Design, enabling you to create entirely new voices tailored to your needs. Amazon Polly, in comparison, provides a limited set of 100 pre-made voices with no capacity for new voice creation.

Voice cloning & design

ElevenLabs support professional voice cloning

ElevenLabs boasts a suite of powerful voice cloning and design capabilities. With Instant Voice Cloning, you can replicate voices quickly from just 30-second audio samples. Professional Voice Cloning offers hyper-realistic, high-fidelity voice clones based on extensive audio inputs. Additionally, the Voice Design tool allows the creation of entirely new voices from a single text prompt.

Amazon Polly, conversely, does not offer voice cloning or design capabilities, limiting users to the voices already provided.

Language support

ElevenLabs supports 32+ languages

ElevenLabs supports voice generation across 32 languages, enabling global reach for multilingual applications. With precise accent control and natural fluency, ElevenLabs allows creators to tailor voices to specific regional audiences with remarkable authenticity. In contrast, Amazon Polly supports 29 languages and offers more limited accent and dialect options, making ElevenLabs the clear choice for diverse, high-quality international voice output.

Voice changer

ElevenLabs supports additional controls with Voice Changer

ElevenLabs offers a Voice Changer product, allowing you to dynamically control emotional tone, speech pace, and overall delivery. Perfect for scenarios requiring on-the-fly adjustments such as interactive storytelling, gaming, and real-time conversational AI, this feature significantly enhances user engagement and emotional resonance—capabilities not found with Amazon Polly.
