Listenhub Voice

When to Use

• User wants end-to-end audio from text (with sound effects baked in by the model)
• User wants a multi-voice dialogue where each line is assigned to a different voice
• User wants to clone a voice from a reference audio clip
• User wants to turn a reference image into audio (image → audio)
• User wants pure sound-effect generation from a text description
• User says "生成音频", "端到端音频", "图片转音频", "多音色对白", "参考音频克隆", "音效"

When NOT to Use

• User just wants a single registered ListenHub voice to read text aloud (use /tts) —

/tts is lower-latency for plain narration with already-registered ListenHub speakers

• User wants a podcast-style discussion with topic exploration (use /podcast)
• User wants music or a cover song (use /music)
• User wants a video (use /video-gen)
• User wants to transcribe audio/video to text (use /asr)

/tts vs /listenhub-voice: /listenhub-voice is the ListenHub-Voice-1.0 end-to-end model — text or image into a finished audio track that can include sound effects, multi-voice dialogue, and reference-audio voice cloning, with an optional durationHint to target an approximate length. Plain single-voice narration with an already-registered ListenHub voice can still go through /tts.

Purpose

Generate end-to-end audio with the ListenHub-Voice-1.0 model. One async task takes a text script (and optionally voices, a reference image, audio params, and a duration hint) and returns a finished audio file. Modes:

• Plain text / sound effects — no voices, no image. The model synthesizes the text

and any sound effects described in it.

• Single voice — voices with 1 item, either a registered ListenHub speaker / Official

voice_type (type: speaker) or a reference-audio clone (type: reference).

• Multi-voice dialogue — voices with 2–3 items; the script assigns each line with

@音频1 / @音频2 prefixes in voices array order. Every item in a multi-voice request must be reference-audio-capable (official voice_type is single-voice only).

• Reference-audio cloning — voices item of type: reference pointing at a public

audio URL to clone that voice.

• Image → audio — an image (url or data). Mutually exclusive with voices.

Hard Constraints

• Always check CLI auth following shared/cli-authentication.md
• Follow shared/cli-patterns.md for CLI execution, errors, and interaction patterns
• Always read config following shared/config-pattern.md before any interaction
• Follow shared/output-mode.md for result presentation — download mode saves

{slug}.{ext} (ext = audioConfig.format: mp3 default / wav / pcm / ogg_opus) to cwd with dedupe per shared/config-pattern.md § Artifact Naming

• Always use the async pattern: submit returns a taskId, then poll the task endpoint

until success / failed — never block waiting on a single call

• image and voices are mutually exclusive — never send both in one request
• Multi-voice (voices length > 1): every item must be reference-audio-capable; a Official

voice_type (type: speaker) is single-voice only and will be rejected in a multi-voice request

• Never expose provider routing, credentials, internal status names, DAO, MongoDB, or

callback internals — work only from the public 3-endpoint contract below

Use the AskUserQuestion tool for every multiple-choice step — do NOT print options as plain text. Ask one question at a time. Wait for the user's answer before proceeding to the next step. After all parameters are collected, summarize the choices and ask the user to confirm. Do NOT call the generate endpoint until the user has explicitly confirmed.

Step -1: CLI Command Gate (ListenHub Voice HTTP fallback)

> ⚠️ CLI status: listenhub-cli does not yet ship a listenhub-voice subcommand. > All examples below therefore call the OpenAPI HTTP contract directly with curl and a > Bearer API Key (lh_sk_...). When a listenhub-voice CLI subcommand ships, this skill should > be updated to prefer it (mirroring /video-gen's $CMD_PREFIX pattern).

Detect whether a future CLI subcommand exists; if not, fall back to HTTP:

if listenhub listenhub-voice --help &>/dev/null; then
  LISTENHUB_VOICE_MODE="cli"
else
  echo "LISTENHUB_VOICE_COMMAND_UNAVAILABLE — falling back to OpenAPI HTTP (curl)"
  LISTENHUB_VOICE_MODE="http"
fi

For http mode, an OpenAPI API Key is required. Read it from config or env:

API_BASE="https://api.marswave.ai/openapi"   # OpenAPI base; see shared/cli-authentication.md
API_KEY="${LISTENHUB_API_KEY:-$(listenhub openapi config show --json 2>/dev/null | jq -r '.apiKey // empty')}"
if [ -z "$API_KEY" ]; then
  echo "需要 OpenAPI API Key（lh_sk_...）。请先用 listenhub openapi config set-key 配置，或设置 LISTENHUB_API_KEY 环境变量。"
fi

All requests authenticate with Authorization: Bearer $API_KEY.

Step 0: Config Setup

Follow shared/config-pattern.md Step 0 (Zero-Question Boot).

If file doesn't exist — silently create with defaults and proceed:

mkdir -p ".listenhub/listenhub-voice"
echo '{"outputMode":"inline"}' > ".listenhub/listenhub-voice/config.json"
CONFIG_PATH=".listenhub/listenhub-voice/config.json"
CONFIG=$(cat "$CONFIG_PATH")

Session defaults (not persisted unless user reconfigures):

• model: listenhub-voice-1.0 (the only valid value)
• audioConfig.format: mp3

Do NOT ask any setup questions. Proceed directly to the Interaction Flow.

If file exists — read config silently and proceed:

CONFIG_PATH=".listenhub/listenhub-voice/config.json"
[ ! -f "$CONFIG_PATH" ] && CONFIG_PATH="$HOME/.listenhub/listenhub-voice/config.json"
CONFIG=$(cat "$CONFIG_PATH")
OUTPUT_MODE=$(echo "$CONFIG" | jq -r '.outputMode // "inline"')

Setup Flow (user-initiated reconfigure only)

Only run when the user explicitly asks to reconfigure. Ask:

1. outputMode: Follow shared/output-mode.md § Setup Flow Question.

Save immediately:

NEW_CONFIG=$(echo "$CONFIG" | jq --arg m "$OUTPUT_MODE" '. + {"outputMode": $m}')
echo "$NEW_CONFIG" > "$CONFIG_PATH"
CONFIG=$(cat "$CONFIG_PATH")

Interaction Flow

Step 1: Collect Text

Ask the user for the script / text to synthesize (required, ≤ 1400 characters, trimmed):

> 输入要合成的文本（≤1400 字）。需要音效就直接在文本里描述；多音色对白用 @音频1 / @音频2 前缀指派每行台词。

Free text. Use as-is — do not modify unless the user asks for help.

Step 2: Voice / Input Mode

Question: "音频用什么音色 / 输入方式？"
Options:
  - "无音色（纯文本 / 音效）" — No voices, no image → Step 3 (audio params)
  - "单个 ListenHub 音色" — voices=[{type:speaker, id:}] → Step 2a
  - "单个官方 voice_type" — voices=[{type:speaker, id:}] → Step 2a
  - "多音色对白（参考音频）" — voices=2–3 项，每项 type:reference → Step 2b
  - "参考音频克隆（单条）" — voices=[{type:reference, url:...}] → Step 2b
  - "图片 → 音频" — image (与 voices 互斥) → Step 2c

Step 2a: Single registered voice (type: speaker)

Collect one speaker id:

• ListenHub voice code — obtained from GET /v1/speakers/list (the registered

ListenHub speakers). Follow shared/speaker-selection.md to let the user pick.

• official voice_type — e.g. zh_female_vv_uranus_bigtts. If the user already knows the

voice_type, use it directly; the server auto-detects ListenHub vs Official codes.

Build: voices = [{ "type": "speaker", "id": "" }]. Proceed to Step 3.

> Note: a official voice_type is single-voice only — it cannot be used in a multi-voice > (>1 item) request.

Step 2b: Reference audio (type: reference)

Each reference item needs a public audio URL (http/https):

• ≤ 30s, ≤ 10MB, format wav / mp3 / pcm / ogg_opus

For single-clip cloning: collect one URL → voices = [{ "type": "reference", "url": "..." }].

For multi-voice dialogue: collect 2–3 reference URLs (max 3 total voices). Every item must be reference-audio (or a mix of ListenHub speakers + reference audio — but not a official voice_type). Then instruct the user to prefix each script line in text with @音频1 / @音频2 / @音频3 matching the voices array order (@音频1 = voices[0]).

Build e.g.:

"voices": [
  { "type": "reference", "url": "https://example.com/host.mp3" },
  { "type": "reference", "url": "https://example.com/guest.mp3" }
]

Proceed to Step 3.

Step 2c: Image → audio (image, mutually exclusive with voices)

Collect one image, either a public URL or Base64 (choose one — not both):

• Max 1 image, ≤ 10MB, format jpeg / png / webp

Build: image = { "url": "https://..." } or image = { "data": "" }. Do not send voices in this mode. Proceed to Step 3.

Step 3: Optional Audio Params

Question: "要调整音频参数吗？（默认：格式 mp3，语速/音量/音调不变）"
Options:
  - "用默认，跳过" — Skip, audioConfig omitted (server uses format mp3)
  - "我要调整" — Ask each below

If adjusting, ask one at a time (all optional, omit any the user doesn't set):

• format: mp3（默认） / wav / pcm / ogg_opus
• speechRate (语速): integer in -50 .. 100
• loudnessRate (音量): integer in -50 .. 100
• pitchRate (音调): integer in -12 .. 12

Build audioConfig with only the fields the user set.

Step 4: Optional Duration Hint

Question: "要指定目标时长吗？（用于积分预估并提示模型生成「约 N 秒」）"
Options:
  - "不指定" — Omit durationHint
  - "指定秒数" — Collect an integer in 1 .. 110

Step 5: Cost Note + Confirmation

> 计费：按实际生成时长（秒）真扣，0.1125 积分/秒，向上取整、最低 1 积分。 > 创建时只做余额预检、不预占；出片后按真实音频时长结算。durationHint 可用于粗略预估 > （约 ceil(durationHint × 0.1125) 积分，实际以出片时长为准）。 > 限流：60 秒内最多 5 次生成。

Present a summary and wait for explicit confirmation before calling generate:

准备生成音频：

  文本: {text 摘要}
  模式: {纯文本/音效 | 单音色(ListenHub/官方) | 多音色对白 | 参考音频克隆 | 图片→音频}
  voices: {无 | N 项}
  image: {无 | url/data}
  audioConfig: {默认 mp3 | 调整后的字段}
  durationHint: {无 | N 秒}
  预估: 约 {ceil(durationHint×0.1125) or "未指定时长，无预估"} 积分（按实结算）

  确认生成？

Execution & Polling

Submit (POST /v1/listenhub-voice/generate → 202)

Build the JSON body from collected values, then POST. The response is 202 with data.taskId and data.status = "pending".

BODY=$(jq -n \
  --arg text "$TEXT" \
  '{ model: "listenhub-voice-1.0", text: $text }')
# Add voices / image / audioConfig / durationHint / watermark only if set, e.g.:
# BODY=$(echo "$BODY" | jq --argjson v "$VOICES_JSON" '. + {voices: $v}')
# BODY=$(echo "$BODY" | jq --argjson img "$IMAGE_JSON" '. + {image: $img}')
# BODY=$(echo "$BODY" | jq --argjson ac "$AUDIOCONFIG_JSON" '. + {audioConfig: $ac}')
# BODY=$(echo "$BODY" | jq --argjson dh "$DURATION_HINT" '. + {durationHint: $dh}')

RESP=$(curl -sS -X POST "$API_BASE/v1/listenhub-voice/generate" \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d "$BODY")
TASK_ID=$(echo "$RESP" | jq -r '.data.taskId // empty')

If TASK_ID is empty, surface the business error (data carries a 33xxx code — see Error Handling). Otherwise: "任务已提交，ID: {TASK_ID}，正在生成中…"

Poll (GET /v1/listenhub-voice/tasks/{taskId})

Run with run_in_background: true. Poll until success / failed:

for i in $(seq 1 120); do
  RESULT=$(curl -sS "$API_BASE/v1/listenhub-voice/tasks/$TASK_ID" \
    -H "Authorization: Bearer $API_KEY" | jq -c '.data')
  STATUS=$(echo "$RESULT" | jq -r '.status')
  case "$STATUS" in
    success) echo "$RESULT"; exit 0 ;;
    failed)  echo "FAILED: $RESULT" >&2; exit 1 ;;
    *) sleep 5 ;;
  esac
done
echo "TIMEOUT" >&2; exit 2

Status flow: pending → generating → uploading → success | failed. (Only these 5 public statuses exist — do not assume any other internal state.)

Result Presentation

On success, parse the ListenHubVoiceTask:

AUDIO_URL=$(echo "$RESULT" | jq -r '.audioUrl')
AUDIO_DURATION=$(echo "$RESULT" | jq -r '.audioDuration')
CREDIT_CHARGED=$(echo "$RESULT" | jq -r '.creditCharged')

Read OUTPUT_MODE from config and follow shared/output-mode.md.

inline or both — display:

音频已生成！

  URL: {audioUrl}
  时长: {audioDuration}s（即计费时长）
  消耗: {creditCharged} 积分

download or both — save to cwd with a topic-based slug per shared/config-pattern.md § Artifact Naming (ext = chosen format, default mp3):

SLUG="{topic-slug}"
EXT="${FORMAT:-mp3}"
NAME="${SLUG}.${EXT}"
BASE="${NAME%.*}"; i=2
while [ -e "$NAME" ]; do NAME="${BASE}-${i}.${EXT}"; i=$((i+1)); done
curl -sS -o "$NAME" "$AUDIO_URL"
echo "已保存到当前目录：$NAME"

On failed: read errorMessage (only present on failure) and show it; suggest checking the script / voices / image and retrying.

On timeout: tell the user to check later with GET /v1/listenhub-voice/tasks/{taskId}.

Querying Past Tasks

List recent tasks (paginated, newest first):

# List (page/pageSize/status/keyword all optional)
curl -sS "$API_BASE/v1/listenhub-voice/tasks?page=1&pageSize=20" \
  -H "Authorization: Bearer $API_KEY" | jq '.data'

# Filter by status + fuzzy keyword on the script text (keyword ≤ 64 chars)
curl -sS "$API_BASE/v1/listenhub-voice/tasks?status=success&keyword=对白" \
  -H "Authorization: Bearer $API_KEY" | jq '.data.items'

# Get one task
curl -sS "$API_BASE/v1/listenhub-voice/tasks/$TASK_ID" \
  -H "Authorization: Bearer $API_KEY" | jq '.data'

List response data: { items: [ListenHubVoiceTask], page, pageSize, total }. status filter accepts pending | generating | uploading | success | failed.
