Amazon Polly is a text-to-speech (TTS) service from AWS that transforms text into lifelike speech using advanced AI models. It supports various voice types and is widely used for applications ranging from virtual assistants to content creation. While Amazon Polly is a powerful platform, its pricing model and feature set may not meet the needs of all users, particularly those looking for more advanced functionality or predictable costs. Play.ht presents itself as a better alternative with transparent pricing and a broader feature set.

Amazon Polly Pricing Breakdown

Amazon Polly charges users based on the number of characters processed. Each type of voice comes with its own cost structure.

Voice TypeCost per 1 Million CharactersFree Tier Allowance (12 Months)
Standard Voices$4.005 million characters per month
Neural Voices$16.001 million characters per month
Long-Form Voices$100.00500,000 characters per month
Generative Voices$30.00100,000 characters per month

Key Features of Amazon Polly

Wide Range of Voices

Amazon Polly offers several types of voices:

  • Standard Voices: Affordable and suitable for basic applications.
  • Neural Voices: More natural, expressive voices designed for conversational interfaces.
  • Long-Form Voices: Ideal for audiobooks or lengthy narrations with consistent delivery.
  • Generative Voices: Advanced AI voices for creative applications.

Real-Time Speech Conversion

Amazon Polly enables real-time text-to-speech processing, making it ideal for live applications like chatbots and voice assistants.

Speech Marks Metadata

Speech Marks allow developers to synchronize audio with visual content, such as highlighting text or creating lip-sync animations.

Integration with AWS Ecosystem

Amazon Polly integrates seamlessly with other AWS services, enabling efficient workflows for developers and enterprises already using AWS infrastructure.

Limitations of Amazon Polly

Escalating Costs

For high-volume users, the pay-as-you-go model can quickly become expensive, particularly with Neural or Long-Form voices. Examples include:

  • Audiobook Production: A novel like “A Christmas Carol” (~165,000 characters) costs $2.64 with Neural voices and $16.50 with Long-Form voices.
  • Conversational Applications: Even small applications requiring 30,000 characters per month cost $0.48 with Neural voices.

Limited Customization

While Polly offers basic control over speed, pitch, and emphasis, it lacks advanced options like emotion-based delivery or voice cloning, which are increasingly important for personalization and branding.

Complexity for New Users

The character-based pricing and multiple voice categories can confuse users unfamiliar with estimating workload costs or selecting the right voice for their needs.

Focus on Developers

Amazon Polly primarily targets developers, with minimal features tailored to content creators, such as audio hosting, podcast tools, or collaboration features.

Play.ht: A Smarter and More Affordable Alternative
