dsh-speak 🔊 — Voice announcements for AI coding harnesses

English · 中文

Let your agent tell you when a long task is done — no more staring at the screen.

dsh-speak reads the final assistant reply aloud through system speech synthesis — on Windows using natural voices (Windows 11 built-in, or NaturalVoiceSAPIAdapter on Windows 10) with graceful fallback to stock voices; on macOS using the built-in say (can follow a Siri natural voice). It was built for DeepSeek Harness and is structured so any harness can plug in.

Project status: this project exists only to provide an already-verified solution for users who want their harness to speak. Barring unexpected circumstances, it will not be updated further.

TL;DR — install for DSH

Install the package into your web profile (pick one):

▼
powershell
复制代码
dsh plugin --profile web add dsh-speak
# or, without pnpm:
npm install --prefix "$env:USERPROFILE\.dsh\profiles\web" dsh-speak

On macOS (bash):

▼
bash
复制代码
npm install --prefix "$HOME/.dsh/profiles/web" dsh-speak

Append to ~/.dsh/profiles/web/cordis.patch.yml:

▼
yaml
复制代码
- insert:
    - id: speech-hook
      name: 'dsh-speak'

Restart the DSH web app — replies are now announced aloud.

Let your agent do it? Paste this repo URL (https://github.com/Alan2Z/dsh-speak) into your DSH session and ask it to install the plugin — your agent follows this very README. Approving the out-of-workspace writes (~/.dsh) is all that's needed.

harness event (DSH session event / Claude Code Stop hook / anything)

      ▼  adapters/…  (harness-specific trigger: filter, throttle, cancel)
      ▼  engine/speak.ps1 / speak.sh  (harness-agnostic: clean text → SAPI5 / say)
      ▼  🔊 you hear the final reply

Features

Automatic: DSH web plugin watches the session event stream and announces the final reply (skips reasoning/tool-call narration, merges multi-step messages).
Gets your attention: announces approval requests (hears "需要你的审批" when the agent is waiting on you) and questions the agent asks via ask_user_question.
Bundle auto-registration (1.3.0): declare the package in dsh.profile.bundles and the plugin registers itself via the bundled cordis.patch.yml — no manual patch entry needed.
Best-effort: never throws, never blocks the harness, never breaks a session.
Natural voices: Windows prefers natural voices — Windows 11 built-in packs, or voices registered via NaturalVoiceSAPIAdapter on Windows 10 (e.g. Xiaoxiao); macOS uses the system reading voice (Siri natural voices on recent macOS). Both fall back to any installed voice.
Robust text cleaning: strips markdown/URLs/emoji that make speech synthesis fail silently, and guards the adapter's per-utterance character ceiling.
Portable engine: any process can speak with one line: Windows powershell -File speak.ps1 -Text "你好" / macOS ./speak.sh -t "你好".

Prerequisites

Windows:

Windows 10 or 11, PowerShell (any recent version).
Natural voices:
- Windows 11: natural voice packs are built into the system — no extra installation. Enable/switch them in Settings → Accessibility → Narrator or Settings → Time & Language → Speech.
- Windows 10: install NaturalVoiceSAPIAdapter and use its VoiceDownloader to download the natural voice pack(s) you want (Chinese or any other language).
Without natural voices, the engine falls back to a stock voice (e.g. Huihui).

macOS:

macOS (Apple Silicon or Intel), built-in say command — no extra software.
Chinese voices: see the macOS section (incl. the Siri natural-voice picker and its pitfalls).

Quick start — DSH

Option A — npm plugin (recommended)

▼
powershell
复制代码
# 1. install the plugin into your web profile (adds dsh-speak to
#    ~/.dsh/profiles/web/package.json dependencies)
dsh plugin --profile web add dsh-speak

# 2. register it in ~/.dsh/profiles/web/cordis.patch.yml
#    (for npm packages the bare package name is used — no file:/// URL needed):
#    - insert:
#        - id: speech-hook
#          name: 'dsh-speak'

# 3. restart the DSH web app — replies are now announced automatically

No pnpm? dsh plugin forwards to pnpm, which is not installed on every machine. The exact same install can be done with npm directly:
▼
powershell
复制代码
npm install --prefix "$env:USERPROFILE\.dsh\profiles\web" dsh-speak

The engine ships inside the package (node_modules/dsh-speak/engine/), so no extra copying is needed.

Option B — file install (no npm needed)

▼
powershell
复制代码
# 1. clone
git clone https://github.com/Alan2Z/dsh-speak.git
cd dsh-speak

# 2. one-command install: copies engine + plugin, registers in cordis.patch.yml
powershell.exe -NoProfile -ExecutionPolicy Bypass -File adapters\dsh\install.ps1

# 3. verify the engine speaks
powershell -NoProfile -ExecutionPolicy Bypass -File "$env:USERPROFILE\.dsh\hooks\speak.ps1" -Text "你好，语音播报已就绪。"

# 4. restart the DSH web app — replies are now announced automatically

What the file installer did:

file	destination
`engine/*.ps1`	`%USERPROFILE%\.dsh\hooks\`
`adapters/dsh/speech-hook.js`	`%USERPROFILE%\.dsh\profiles\web\plugins\`
registration entry	appended to `%USERPROFILE%\.dsh\profiles\web\cordis.patch.yml` (backed up first)

macOS

The same adapter runs natively on macOS — the plugin auto-detects the platform and calls engine/speak.sh (the built-in say command) instead of speak.ps1. Since 1.2.0 the macOS engine ships in the npm package — no extra software.

Install (npm — same as Windows)

▼
bash
复制代码
# 1. install into your web profile (no pnpm needed — only `dsh plugin` requires it)
npm install --prefix "$HOME/.dsh/profiles/web" dsh-speak

# 2. register in ~/.dsh/profiles/web/cordis.patch.yml (bare package name — no file:/// URL):
#    - insert:
#        - id: speech-hook
#          name: 'dsh-speak'

# 3. no restart needed — the patch watcher hot-reloads; pure-text replies are
#    announced after ~1.5 s (tool-calling replies are intentionally not announced)

With pnpm installed, dsh plugin --profile web add dsh-speak works identically.

Voices (important — two pitfalls)

By default the engine follows the system reading voice (Settings → Accessibility → Spoken Content → System Voice). On macOS 26 that picker has an ⓘ circle icon next to it — click it for the full voice list; the plain dropdown does not contain the Siri natural voices. Pick e.g. "普通话 Siri 声音1（男声）" there.
Siri voice (Settings → Siri → Voice) and the system reading voice are two independent settings; Siri voices are not exposed to say -v '?' and cannot be selected by name — they only work as the system default.
⚠️ Pitfall 1 (reproduced): opening the "Spoken Content / Siri Voice" settings pane — even without changing anything — drifts/resets the system voice to the classic "婷婷 (Tingting)". If the voice suddenly changes, re-pick it via the ⓘ entry.
⚠️ Pitfall 2: the log lives at $TMPDIR/dsh-speech-hook.log (os.tmpdir() — not /tmp).
Use -v Eddy|Flo|Tingting to force a specific voice (say -v '?' lists them).
say has no volume flag — volume follows the system output volume.

Test the engine alone (no DSH needed)

▼
bash
复制代码
curl -sfL -o ~/speak.sh "https://cdn.jsdelivr.net/gh/Alan2Z/dsh-speak@main/engine/speak.sh"
chmod +x ~/speak.sh
~/speak.sh -t "你好，Mac 版语音播报测试"
~/speak.sh -t "测试" -v Eddy -r 200              # explicit voice + rate

Quick start — Claude Code

          }
        ]
      }
    ]
  }
}

Quick start — any other harness

Call the engine directly from your agent / wrapper / script:

▼
powershell
复制代码
# announce a one-liner
powershell -NoProfile -ExecutionPolicy Bypass -File engine\speak.ps1 -Text "构建完成"

# announce a long summary (from a file)
powershell -NoProfile -ExecutionPolicy Bypass -File engine\speech-summary.ps1 -Text "…"

# ask for user attention (blocking, for prompts/approvals)
powershell -NoProfile -ExecutionPolicy Bypass -File engine\speech-prompt.ps1 -Text "请做出选择"

Configuration

Engine parameters (see docs/DESIGN.md):

▼
powershell
复制代码
speak.ps1 -Text "…" -Volume 50 -Rate 1 -MaxChars 300 -LongTextMessage "本次播报内容较长，请自行阅读。"

DSH plugin configuration — prefer the profile patch config block (visible in dsh --dump-config, per-profile, survives npm updates):

▼
yaml
复制代码
# ~/.dsh/profiles/web/cordis.patch.yml
- insert:
    - id: speech-hook
      name: 'dsh-speak'
      config:
        throttleMs: 1500        # merge delay before announcing (ms)
        engine: ''              # engine path override; '' = auto-resolve
        announceApprovals: true # speak approval requests
        announceQuestions: true # speak ask_user_question content
        stripApprovalPrefix: true  # strip the "escalate sandbox to ...: " prefix
        longTextMode: message   # message | heading (speak largest md heading)
        maxChars: 300           # engine per-utterance ceiling
        volume: 50              # Windows only
        rate: 0                 # 0 = engine default (Windows SAPI scale / macOS wpm)

See docs/CUSTOMIZATION.md for the full customization guide.

Customizing (survives npm updates)

You can tune behavior without forking, and your changes survive npm update:

Copy the engine out and edit it (recommended — this is where defaults live: volume, rate, MaxChars, LongTextMessage, voice logic):

▼
powershell
复制代码
# Windows
Copy-Item "$env:USERPROFILE\.dsh\profiles\web\node_modules\dsh-speak\engine\speak.ps1" "$env:USERPROFILE\.dsh\hooks\my-speak.ps1"
# macOS
cp ~/.dsh/profiles/web/node_modules/dsh-speak/engine/speak.sh ~/.dsh/hooks/my-speak.sh

Then point the plugin at your copy in the config block:

▼
yaml
复制代码
- insert:
    - id: speech-hook
      name: 'dsh-speak'
      config:
        engine: 'C:/Users/<you>/.dsh/hooks/my-speak.ps1'   # or ~/.dsh/hooks/my-speak.sh on macOS

The plugin resolves the engine as config.engine → package engine → ~/.dsh/hooks/, so your copy wins. npm update only touches the package — your engine stays.

Edit the file inside node_modules — works, but the next npm update overwrites it.
Fork the repo — full control, publish your own package if you want.

Troubleshooting

symptom	cause	fix
No sound at all, no error	no natural voice enabled/installed	Win11: enable a natural voice in Settings → Narrator / Speech; Win10: install NaturalVoiceSAPIAdapter + a voice pack. Test `speak.ps1` directly
Long replies never spoken	adapter per-`Speak` character ceiling	already guarded at 300 chars — lower `-MaxChars` if needed
Emoji-heavy text silent	SAPI fails silently on emoji	already stripped by the engine
Plugin not loading	raw Windows path as plugin name	use the `file:///C:/…` URL form (installer does this)
macOS: voice suddenly became "婷婷"	opening the "Spoken Content / Siri Voice" pane drifted the system voice	re-pick via Settings → Accessibility → Spoken Content → System Voice → ⓘ entry
macOS: no log at `/tmp`	`os.tmpdir()` is `/var/folders/.../T`, not `/tmp`	log is at `$TMPDIR/dsh-speech-hook.log`

Plugin diagnostics: Windows %TEMP%\dsh-speech-hook.log; macOS $TMPDIR/dsh-speech-hook.log

Writing a new adapter

Three reference patterns exist: event-stream (DSH), stop-hook (Claude Code), agent-called (speech-summary.ps1 from a shell). In every case the adapter only needs to: capture the final reply text → invoke the engine. See docs/DESIGN.md §7.
