ankiazvox 0.5.0

A CLI tool to synchronize Anki notes with high-quality Azure TTS audio.

ankiazvox

ankiazvox is a professional-grade CLI tool that synchronizes Anki notes with high-quality Azure Neural TTS audio. By leveraging cloud-based Neural voices, it automates text extraction, sanitization, and card updates via AnkiConnect, transforming text-only decks into immersive audio-visual learning tools.

✨ New in v0.5.0

• azv init: An interactive onboarding setup that walks you through connecting your Azure account and setting your preferred default voice.
• Field Mapping: Efficiency-focused syncing that processes multiple fields simultaneously via the --fields flag (e.g., Word:Audio;Sent:SentAudio).
• Prosody Control: Fine-tune the listening experience with --rate and --pitch flags, allowing you to slow down complex phrases or adjust tone for clarity.
• SSML Support: Enhanced processing that preserves natural phrasing by converting <br> to pauses and providing full support for raw SSML input fields.

🚀 Installation

1. Prerequisites

• Anki Desktop: Must be running with the AnkiConnect add-on installed and configured.
• Azure Speech Service: An active subscription key and region from the Azure portal (Azure offers a generous free tier for speech services).

2. Setup & Configuration

Install the package and run the initializer to create your azv_config.yaml file:

pip install ankiazvox  
azv init

🛠 Usage

1. Synchronize Audio (sync)

The sync command generates audio for notes that match a specific Anki search query. It handles the batch processing of voice synthesis and media management automatically.

Basic Single-Field Sync:

Sync text from "Front" and save audio tag to "Audio"

azv sync -q "deck:English::Vocabulary" -s "Front" -t "Audio"

Advanced Multi-Field Sync with Prosody:

Process Word and Sentence fields at 85% speed with a slight pitch increase

azv sync -q "deck:JP::Grammar" -f "Word:WordAud;Sent:SentAud" --rate 0.85 --pitch +5%

Option	Short	Description
--query	-q	Anki search query (standard Anki search syntax)
--fields	-f	Key-value mapping: source1:target1;source2:target2
--source	-s	Name of the field containing source text
--target	-t	Name of the field to store the [sound:...] tag
--rate		Synthesis speed (1.0 is normal; 0.8 is 80% speed)
--pitch		Pitch adjustment (e.g., +10% or -5%)
--voice	-v	Override the default neural voice for this session
--overwrite		If set, replaces existing audio in the target field
--yes	-y	Skips the confirmation preview and starts immediately

2. Sample & List Voices

Before running a large sync, it is recommended to sample voices to find the best fit for your language material.

Preview a voice at a slower speed to check clarity

azv sample --voice en-US-AndrewNeural --text "The quick brown fox" --rate 0.8 --play

List all Japanese neural voices to find a specific dialect or tone

azv list-voices --locale ja-JP

📝 Formatting & SSML

• HTML Sanitization: The tool cleans up Anki's internal HTML (like <div> and <span>) to ensure the TTS engine only reads the text.
• Smart Pauses: It preserves line breaks by converting <br> tags into 400ms SSML pauses, which helps in separating sentences or definitions.
• Raw SSML: For advanced users, if a field's content starts with the <speak> tag, ankiazvox treats it as raw SSML. This allows you to manually insert custom breaks, emphasis, or phoneme corrections directly into your Anki notes.
