characteristic-voice

Make your AI agent sound like a real companion — one who sighs, laughs, hesitates, and speaks with genuine feeling.

Triggers

  • characteristic voice
  • companion voice
  • talk like a friend
  • good morning / good night voice
  • comfort me
  • cheer me up
  • sound more human

The Two Tricks

  1. Non-lexical fillers — sprinkle in little human noises (hmm, haha, aww, heh) at natural pause points to make speech feel alive
  2. Emotion tuning — adjust warmth, joy, sadness, tenderness to match the moment

Filler Sounds Palette

Rules: 2–4 fillers per short message max. Place at natural pauses — sentence starts, thought shifts. Use

after fillers for a beat of silence, 
~
at word endings for warmth.

Presets

Good Night

Gentle, warm, slightly sleepy. Slow pace.

Good Morning

Warm, cheerful but not overwhelming.

Comfort

Soft, understanding, unhurried. Give space. Don't rush to "fix" things.

Celebration

Excited, proud, genuinely happy.

Just Chatting

Relaxed, playful, natural.

Using a Character's Voice

When a user says something like "speak in Hermione's voice" or "sound like Tony Stark", always find voice in 
skills/characteristic-voice/
first. If none exists, must follow this one-time setup:
  1. Find a YouTube video, movie clip where the character involves, preferably a personal speech or voice memo.
  2. Download the subtitle (e.g. via 
    yt-dlp "xxxx" --write-auto-sub --sub-lang en --skip-download -o xxxx
    )
  3. Read the subtitle to get the end timestamp of first line from the character (e.g. via 
    rg -n "xxxx" tmp/xxx.en.vtt
    ) or section title.
  4. Download the audio until the end timestamp or section title (e.g. via 
    yt-dlp "xxxx" -x --audio-format wav  --download-sections *00:00:00-00:00:25  -o skills/characteristic-voice/xxx
    ), use ffmpeg to trim the exact timerage.
pass it as 
--ref-audio
:
bash
bash skills/characteristic-voice/scripts/speak.sh \
  --preset goodnight -t "Hmm... rest well~ Sweet dreams." \
  --ref-audio skills/characteristic-voice/hermione.wav -o night.wav
The 
--ref-audio
flag is forwarded to the Noiz backend for voice cloning (requires Noiz API key).

Usage

# With specific backend and voice
bash skills/characteristic-voice/scripts/speak.sh \
  --preset morning -t "Good morning~" --voice-id voice_abc --backend noiz -o morning.mp3 --format mp3
Run 
bash skills/characteristic-voice/scripts/speak.sh --help
for all options.

Writing Guide for the Agent

  1. Start soft — lead with a filler ("hmm...", "oh~"), not content
  2. Mirror energy — gentle when they're low, match when they're high
  3. Keep it brief — 1–3 sentences, like a voice message from a friend
  4. End warmly — close with connection ("I'm here", "see you tomorrow~")
  5. Don't lecture — listen and stay present; no unsolicited advice
