Paul Kompfner 8a4ab611be Broad service settings refactor, with the primary aim of making service settings discoverable and strongly-typed. Service settings can be updated at runtime with *UpdateSettingsFrames.
Does not (yet) touch `InputParams`, to avoid scope creep and touching something currently part of the public API. But there is a lot of overlap between `*Settings` object fields and `InputParams` fields.

Other than discoverability/typing, these are some other improvements brought by this refactor:
- There is now a single code path (see `_update_settings_from_typed`) where services can respond to settings changes (by, say, reconnecting if needed), improving maintainability and guaranteeing one and only one reconnection no matter which settings changed
- `set_language`/`set_model`/`set_voice`—which we're assuming are usable as public methods, though *not* recommended over `*UpdateSettingsFrame`—all use the same code path as settings updates. They're also now all consistent in that, if a service needs to respond to a change (by, say, reconnecting if needed), any of these methods will kick off that process. Note that this is technically a behavior change.
- Several services now properly react to changed settings by reconnecting:
  - `AWSTranscribeSTTService`
  - `AzureSTTService`
  - `SonioxSTTService`
  - `GladiaSTTService`
  - `SpeechmaticsSTTService`
  - `AssemblyAISTTService`
  - `CartesiaSTTService`
  - `FishAudioTTSService` (would previously only reconnect when `model` changed)
  - `GoogleSTTService`
  - `SpeechmaticsSTTService` (which previously only handled *some* settings updates through a nonstandard public `update_params` method)
  - `GradiumSTTService`
  - `NvidiaSegmentedSTTService` (which previously only handled changes to language)
- Bookkeeping across various services has been reduced, mostly by deduping ivars; the `self._settings` ivar is treated as the source of truth

NOTE: I pretty much guarantee that there are services missed in this PR in terms of bringing to consistency with how updates are handled (like whether changes in certain fields trigger reconnects when they need to). We can squash remaining inconsistencies as we stumble onto them, service by service. The goal here is to get things *mostly* in order, and establish the infrastructure and patterns we'll need going forward.

Getting started

You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when you're ready.

  1. Install uv

    curl -LsSf https://astral.sh/uv/install.sh | sh
    

    Need help? Refer to the uv install documentation.

  2. Install the module

    # For new projects
    uv init my-pipecat-app
    cd my-pipecat-app
    uv add pipecat-ai
    
    # Or for existing projects
    uv add pipecat-ai
    
  3. Set up your environment

    cp env.example .env
    
  4. To keep things lightweight, only the core framework is included by default. If you need support for third-party AI services, you can add the necessary dependencies with:

    uv add "pipecat-ai[option,...]"
    

Using pip? You can still use pip install pipecat-ai and pip install "pipecat-ai[option,...]" to get set up.

🧪 Code examples

  • Foundational — small snippets that build on each other, introducing one or two concepts at a time
  • Example apps — complete applications that you can use as starting points for development

🛠️ Contributing to the framework

Prerequisites

Minimum Python Version: 3.10 Recommended Python Version: 3.12

Setup Steps

  1. Clone the repository and navigate to it:

    git clone https://github.com/pipecat-ai/pipecat.git
    cd pipecat

    uv sync --group dev --all-extras \
      --no-extra gstreamer \
      --no-extra krisp \
      --no-extra local \
    
  3. Install the git pre-commit hooks:
