Voice Clone

Clones a voice from a reference audio URL via giggle.pro. Flow: submit voice-clone with file.url directly → script polls until completed. Returns full signed audio URLs. Tell the user before the long-running exec that generation is in progress and you will return as soon as the script finishes (see Continuous progress updates).

API Key: Set system environment variable GIGGLE_API_KEY. Obtain it at giggle.pro while logged in: left sidebar → API Key (API 密钥). The script will prompt if not configured.

No inline Python: All commands must be executed via the exec tool. Never use heredoc inline code.

No Retry on Error: If script execution encounters an error, do not retry. Report the error to the user directly and stop.

Execution Flow

Voice cloning typically takes 1–3 minutes. The script submits voice-clone with file.url directly (no upload step), then polls for result.

Important: Never pass GIGGLE_API_KEY in exec's env parameter. API Key is read from system environment variable.

Continuous progress updates (default; user need not put this in their prompt)

One exec runs the whole flow: submit + poll until done (--max-wait, default 180s). There is no separate --query loop for you to run.

1. Before the script, tell the user cloning/synthesis started, typical wait ~1–3 minutes, and you will paste signed audio links or errors when the command finishes—never start a long run with zero message.
2. Do not wait for the user to say “check status” before launching the script after that preamble.
3. When the script exits, immediately forward stdout (URLs or errors) in natural language; on timeout at --max-wait, explain and suggest retry or a different sample/voice_id.
4. If the user wants zero preamble, use one minimal line only, then run the script.

Step 1: Guide User to Provide Requirements

Before running, you must collect:

1. Audio URL – A publicly accessible URL of the reference audio (e.g. MP3, WAV). User provides a link to the sample they want to clone.
2. voice_id – User-defined. Must be unique per clone. Example: my_voice_001, minimax_testasds_02. If duplicate, API returns voice clone voice id duplicate.
3. Text – The text to synthesize with the cloned voice (e.g. "A gentle breeze sweeps across the soft grass...").

Step 2: Run Full Flow

Before the command below, send the user the short preamble described above.

python3 scripts/voice_clone_api.py \
  --audio-url "https://example.com/voice_sample.mp3" \
  --text "A gentle breeze sweeps across the soft grass, carrying the fresh scent." \
  --voice-id "my_unique_voice_01" \
  --need-noise-reduction false \
  --need-volumn-normalization false

Optional parameters:

• --need-noise-reduction (default: false): Apply noise reduction to cloned audio
• --need-volumn-normalization (default: false): Apply volume normalization

---

Step 3: Handle Output

Success: Script outputs the full signed audio URL(s). Forward to user as-is.

Failure:

• voice clone voice id duplicate: Guide user to choose a different voice_id
• Other errors: Report error message to user

---

Link Return Rule

Audio links returned to the user must be full signed URLs (with Policy, Key-Pair-Id, Signature query params). Do not strip response-content-disposition=attachment when the API returns it. The script only normalizes ~ → %7E; keep URLs as-is when forwarding.

Parameter Reference

Parameter	Required	Default	Description
--audio-url	yes	-	Public URL of reference audio to clone
--text	yes	-	Text to synthesize with cloned voice
--voice-id	yes	-	User-defined unique voice identifier; must not duplicate existing
--need-noise-reduction	no	false	Apply noise reduction
--need-volumn-normalization	no	false	Apply volume normalization
--max-wait	no	180	Max wait seconds for clone task

Interaction Guide

When the user initiates voice clone:

1. Ask: "Please provide a publicly accessible URL to the reference audio to clone."
2. Ask: "Please choose a unique voice_id for this clone (e.g. my_voice_001); it must not duplicate an existing clone."
3. Ask: "Please provide the text to synthesize with the cloned voice."
4. After the user provides all three, run the script and forward the output.

If voice_id duplicate: "That voice_id is already in use—please pick another unique id and try again."
