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
        +  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: 0.7

Step 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 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.mp3

If the user wants a different story or age group, regenerate only the story text and re-synthesize — the program structure stays the same.
