SenseAudio Bedtime Radio
Generate a complete bedtime story audio program — not just a TTS read-aloud, but a structured radio-style show with intro, paced narration, character voices, and a sleepy outro.
Step 1: Collect Inputs
Ask the user for:
- 故事关键词 — e.g., "月亮上的小兔子", "会飞的小猪", "森林里的魔法书"
- 孩子年龄 — affects vocabulary and story complexity (default: 4–6岁)
- 时长偏好 — 短版 (~2分钟) / 标准版 (~4分钟) / 长版 (~6分钟)
Step 2: Write the Story (LLM task)
Generate the story yourself — no API call needed for this step. Follow these rules based on age:
| Age | Vocabulary | Sentence length | Story complexity |
|---|---|---|---|
| 2–3岁 | 极简，常用词 | ≤10字/句 | 单线情节，重复句式 |
| 4–6岁 | 简单，生动 | 10–18字/句 | 简单起承转合 |
| 7–10岁 | 丰富，有细节 | 15–25字/句 | 有悬念和转折 |
Story structure:
- 开头：交代主角和场景（1段）
- 发展：遇到问题或冒险（2–3段）
- 高潮：解决问题的关键时刻（1段）
- 结尾：温馨收尾，引导入睡（1段，语气渐缓）
Length guide:
- 短版：约300字
- 标准版：约600字
- 长版：约1000字
Mark dialogue lines with the character name: [小兔子]: "..." [老爷爷]: "..."
Step 3: Plan the Audio Program
Structure the full program before making any API calls:
[片头] "晚安，小朋友。今天的故事叫做《<标题>》。"
voice: female_0006_a, speed: 0.9
[正文段落1] 旁白第一段
voice: female_0006_a, speed: 0.85
+ <break time="2000"> after paragraph
[对话] 角色台词（如有）
小动物/儿童角色 → child_0001_b, speed: 0.9
老人/长辈角色 → male_0004_a, speed: 0.85
旁白继续 → female_0006_a
[正文后半段] speed 逐段降低：0.85 → 0.80 → 0.75
模拟催眠节奏
[片尾] "故事讲完啦，闭上眼睛，晚安……"
voice: female_0006_a, speed: 0.7Step 4: Synthesize Each Segment
Generate each segment as a separate mp3 file, then list them for the user to assemble.
Segment synthesis pattern:
synthesize() {
local TEXT="$1"
local VOICE="$2"
local SPEED="$3"
local OUTFILE="$4"
curl -s -X POST https://api.senseaudio.cn/v1/t2a_v2 \
-H "Authorization: Bearer $SENSEAUDIO_API_KEY" \
-H "Content-Type: application/json" \
-d "{
\"model\": \"SenseAudio-TTS-1.0\",
\"text\": \"$TEXT\",
\"stream\": false,
\"voice_setting\": { \"voice_id\": \"$VOICE\", \"speed\": $SPEED },
\"audio_setting\": { \"format\": \"mp3\" }
}" -o "${OUTFILE}.json"
jq -r '.data.audio' "${OUTFILE}.json" | xxd -r -p > "$OUTFILE"
echo "$(jq '.extra_info.audio_length' "${OUTFILE}.json")ms — $OUTFILE"
}Segment breakdown:
| Segment | Text | Voice | Speed | File |
|---|---|---|---|---|
| 片头 | "晚安，小朋友。今天的故事叫做《<标题>》。" | female_0006_a | 0.9 | 00_intro.mp3 |
| 正文段1 | 第一段旁白 | female_0006_a | 0.85 | 01_narration.mp3 |
| 正文段2 | 第二段旁白 | female_0006_a | 0.85 | 02_narration.mp3 |
| 对话（如有） | 角色台词 | child_0001_b / male_0004_a | 0.9 | 03_dialogue.mp3 |
| 正文段3 | 后半段旁白 | female_0006_a | 0.80 | 04_narration.mp3 |
| 正文段4 | 结尾段旁白 | female_0006_a | 0.75 | 05_narration.mp3 |
| 片尾 | "故事讲完啦，闭上眼睛，晚安……" | female_0006_a | 0.7 | 06_outro.mp3 |
Insert <break time=2000> at paragraph boundaries within a segment's text to create natural pauses between paragraphs.
Step 5: Output
List all generated files with durations and assembly instructions:
睡前故事电台生成完成：《<标题>》
文件列表（按顺序播放）：
00_intro.mp3 — 片头 (8秒)
01_narration.mp3 — 第一段 (42秒)
02_narration.mp3 — 第二段 (38秒)
03_dialogue.mp3 — 对话 (25秒)
04_narration.mp3 — 第三段，渐慢 (45秒)
05_narration.mp3 — 结尾段，更慢 (40秒)
06_outro.mp3 — 片尾 (12秒)
总时长：约 3分50秒
合并命令（需要 ffmpeg）：
ffmpeg -i "concat:00_intro.mp3|01_narration.mp3|..." -acodec copy story.mp3If the user wants a different story or age group, regenerate only the story text and re-synthesize — the program structure stays the same.
