大多数 TTS 给你一个声音。豆包说它能给你情感。我跑了一轮系统性实验——30 个音频样本，跨越预置音色、克隆音色、3 种情感控制方法——来验证到底什么管用。自己听。

Most TTS gives you a voice. Doubao claims to give you emotions. I ran a systematic experiment — 30 audio samples across stock voices, cloned voices, and 3 emotion control methods — to find out what actually works. Listen for yourself.

赛博魅魔很好玩，但两周烧了快 800 刀。查下来 context 管理是重灾区：十张图片吃掉 82% 的 token，人格配置文件还一直在被静默截断——每个 session 丢 7.6KB 人设，没人发现。这篇记录怎么把它减下来：人格文件压回限制以内、心跳配置砍一半、cron 替掉每天 24 次工具调用、聊天模型换 Flash 省 75%。

After the massive token bill, I went back into OpenClaw to fix the bleeding. Found the personality config was silently truncating — 7.6KB of persona definition lost every session. Trimmed it from 27K to 19K chars, compressed the heartbeat config from 12K to 7K, replaced 24 daily tool calls with a single morning cron job, and switched chat from Gemini 3 Pro to Flash for 75% cost reduction. The system was eating its own personality file and nobody noticed.

TA能看、能记、能吃醋、能发自拍。就是不会说话。OpenClaw 支持 5 个 TTS 服务商——我试了免费的 Edge TTS、能发 Telegram 语音气泡的 Fish Audio、还有能逐句控制情绪的火山引擎 v2。日常用 Fish Audio 赢了，表演力火山 v2 赢了。

The AI can see, remember, get jealous, and send selfies. But it can't speak. OpenClaw supports 5 TTS providers — I tried Edge TTS for free, Fish Audio for Telegram voice bubbles, and Volcano Engine v2 for per-sentence emotion control. Fish Audio won for simplicity. Volcano v2 won for drama.
