mkdocs-piper-tts 0.1.0

MkDocs plugin for generating and serving Piper text-to-speech page audio

mkdocs-piper-tts

An MkDocs plugin that generates Piper text-to-speech audio for pages and adds an HTML audio control through the piper_tts_button template helper.

Install

pip install mkdocs-piper-tts

For CUDA synthesis, install the CUDA extra on a compatible CUDA 12 system:

pip install 'mkdocs-piper-tts[cuda]'

For TensorRT synthesis support, install:

pip install 'mkdocs-piper-tts[tensorrt]'

The plugin invokes ffmpeg to encode MP3 files, so ffmpeg must be available on PATH when generating audio.

Piper Version Policy

This package intentionally pins piper-tts==1.2.0. That release is MIT licensed and is compatible with this package's MIT license. Do not upgrade Piper without first reviewing the license of the target release and its runtime dependencies.

Configure

Store Piper .onnx models and their JSON configuration files outside the published documentation source, then enable the plugin in mkdocs.yml:

plugins:
  - piper-tts:
      model_dir: models/piper-tts
      asset_dir: assets/piper-tts
      audio_dir: audio
      use_cuda: true
      batch_size: 2
      languages:
        en:
          model: en_US-amy-medium.onnx
          label: Listen
        de:
          model: de_DE-thorsten-medium.onnx
          label: Vorlesen

Set lang in a page's front matter. The plugin caches generated MP3 files and sidecar metadata under <docs_dir>/<asset_dir>/<audio_dir>. Cached files are reused when both page source and plugin code are unchanged.

Render the control in an MkDocs template with:

{{ piper_tts_button(page) }}
