mypy-boto3-polly
Type annotations for boto3 Polly 1.43.0 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes. This is a low-friction, actively maintained type stub with no security issues, permissive MIT licensing, and a single lightweight dependency. Install it if you use boto3 with Polly and want IDE autocomplete and static type checking; it adds no runtime overhead and is safe to use in production environments.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; boto3 must be installed separately in your environment.
- Low friction install with a single lightweight runtime dependency (typing-extensions).
- Actively maintained with recent releases and a stable repository.

What it is and what it does
mypy-boto3-polly is a stub package that adds complete type annotations for AWS Polly operations when using boto3. It enables IDEs like VSCode, PyCharm, Emacs, and Sublime Text to provide accurate code completion and type checking, and works with static type checkers including mypy and pyright. The package is generated from boto3 1.43.0 and requires only typing-extensions as a runtime dependency.
The stubs allow developers to write boto3 code with full type safety without explicit type annotations. It supports Polly clients, paginators, and type definitions, and can be installed standalone or as part of boto3-stubs with the [polly] extra. The package is actively maintained, supports Python 3.9 through 3.14, and carries no known vulnerabilities.
Use it for
- Enable IDE autocomplete and type hints when calling Polly APIs in a boto3 application.
- Catch type errors in Polly service calls during development with mypy or pyright before runtime.
- Provide accurate type information for Polly paginators and client methods in a team codebase.
- Reduce debugging time by catching incorrect Polly parameter types or missing required fields at type-check time.
- Use in a VSCode or PyCharm project to get real-time type checking feedback while writing Polly integration code.
