Otoha TTS
Otoha395 downloadsRead the current note aloud — device voice, or high-quality neural voices via the free Otoha app — with sentence highlighting and smooth follow-scrolling.
- Overview
- Scorecard
- Updates1
Read the current note aloud in Obsidian, highlighting each sentence in place and smooth-scrolling to follow the spoken line.
Works standalone with your device's built-in speech (no setup, no server, works offline and on mobile). For higher-quality neural voices, install the free Otoha app — a menu-bar app that bundles and runs everything locally (no cloud, no accounts).
Features
- Read the whole note, the current selection, or from the cursor.
- In-place sentence highlighting that follows along as it reads.
- Smooth "teleprompter" auto-scroll that keeps the spoken line in view.
- Click any sentence while reading to jump there; play / pause / stop.
- Two engines: Device (built-in OS speech, default, offline) or Otoha (high-quality neural voices via the free Otoha app — all local).
Install
From the community plugins browser (once listed): Settings → Community plugins → Browse → search "Otoha TTS" → Install → Enable.
Manually: download main.js, manifest.json, and styles.css from the
latest release into
<vault>/.obsidian/plugins/otoha-tts/, then enable the plugin.
Engines
- Device (default): uses the OS built-in speech synthesis. Nothing to install, works offline and on mobile.
- Otoha (neural voices): install the free Otoha app
(download). It runs a local
Kokoro server on your machine and the plugin talks
to it at
http://127.0.0.1:8765— all local, no cloud. Then pick the Kokoro engine in the plugin settings. (Advanced: you can run your own Kokoro server on that port instead of the app.)
Network use (full disclosure)
This plugin only ever talks to localhost — it makes no external/internet requests:
- Kokoro engine: HTTP requests to
http://127.0.0.1:8765(only when you choose the Kokoro engine) to synthesize audio. - Companion app integration (desktop only): to let the optional Otoha menu-bar app
mirror and control playback, the plugin opens a small loopback HTTP listener on
127.0.0.1:8767and posts playback state to127.0.0.1:8766. These bind to localhost only and are best-effort (skipped if the port is busy or unavailable, e.g. on mobile).
No telemetry, no analytics, no remote code.
Development
Plain JS, no build step. Pure logic (sentence parsing, text matching, scroll math) has unit tests:
