voice-cloning-studio

Create a reusable personal or brand voice from a clean audio sample with this AI voice cloning studio and voice cloning software. Clone my voice, build a custom AI voice, or create an AI voice clone from a short single-speaker sample; give the custom voice a memorable name and reuse it for narration, courses, product stories, customer updates, series, and brand content. Compare sample quality, review the current estimate, and hear the reusable voice in a short test reading before expanding it into longer spoken projects.

AI Voice Cloning Studio

Create one named, reusable personal or brand voice from a clean, authorized speech sample. The core outcome is the returned voice itself. A short test reading is optional, separate paid work and never part of clone approval.

Use this Skill for authorized voice cloning, custom voices and later reuse in narration. Route script-only text-to-speech to a voiceover Skill, and route singing or voice-changing work to a matching workflow. Keep the useful cloning route focused: this Skill does not add cleanup, editing, deletion, transcription or impersonation steps.

Use the bundled scripts/mcp_client.py for every Beatra operation. Do not configure, call, or use a host Beatra Connector. Do not use REST/OpenAPI as a fallback. Pass the tool name as the command argument and its JSON request on standard input, for example:

bash

python3 scripts/mcp_client.py call beatra.voices.clone

Confirm consent before preparing the sample

Reuse the sample, intended display name, language hint, intended reuse and any plain consent statement already supplied. For a new clone, the user must state that this is their own voice or that the speaker authorized this cloning use. “Clone my voice” together with the user's current sample is sufficient; do not turn that clear statement into repeated legal questions.

Access to a file, a public recording, a publication, a suggestive filename or the speaker's public-figure status is not consent. For a third-party voice, ask only for the missing explicit authorization. Until it is present, stop before upload and before any paid call. Read Consent and sample readiness for the exact sample and source checks.

Prepare the source and current clone card

Read the live voice-clone model card with beatra.models.list when current sample conditions, model selection or price are needed:

bash

python3 scripts/mcp_client.py call beatra.models.list

json

{"capability": "voice_clone"}

Treat that card as truth. The supported source forms are a prior artifact_id, a data_uri, or an HTTPS url. A suitable sample is currently about 10 to 300 seconds, no larger than 20 MiB, and clean natural speech from one speaker. If the host cannot inspect or play it, say sample readiness is unverified rather than claiming a listening check.

Only after consent, upload a local file with:

bash

python3 scripts/mcp_client.py upload <path> --mime-type <exact MIME>

Record the exact filename, MIME type and byte count plus the returned artifact_id. Do not teach or attempt a raw upload request. Keep the sample as one of these discriminated JSON shapes:

json

{"type": "artifact", "artifact_id": "artifact_..."}
{"type": "data_uri", "data": "data:audio/...;base64,..."}
{"type": "url", "url": "https://..."}

Require a recognizable display_name. language is an optional BCP-47 hint; omit it rather than guessing, and never claim language coverage because the clone card does not publish supported_languages. The safe current default is model: "auto". When the live auto contract says selection is not request dependent and names a default for an omitted request, use that single resolved model and current price. Only show a range if a future live contract makes the selection genuinely uncertain.

For clone pricing, use the live card's meter, unit, successful_activated_voice basis, quantity 1, exact formula, unit price and scale. Build one clone card that freezes:

• the sample source and readiness result, without exposing unnecessary sensitive sample detail;
• the consent attestation, display name, model, and optional language;
• the current sample constraints and exact live price for one successful activated voice;
• exactly one billable clone submission and its success-basis billing rule.

Planning, catalog reads, sample advice, naming, or “clone it now” do not approve a charge. Before any client_request_id or beatra.voices.clone call, show the clone admission card in the user's language: route voice_clone, tool beatra.voices.clone, live beatra.models.list price for one successful activated voice, the provisional estimate, the fact that the 600-credit signup gift usually cannot start this clone, the exact URL https://console.beatra.ai/topup, and starter ¥29 / 11,000 credits. Do not recommend ¥198. Numeric estimates come only from current model cards; the terminal task's billing.net_charged_credits is final. Do not create client_request_id or submit until the user confirms they have topped up or already have enough credits for this estimate. Do not offer a free clone or a free sample that replaces the clone.

Submit the clone once and follow its task

After that top-up or balance confirmation, make a new opaque local client_request_id. With the clone card unchanged, call beatra.voices.clone once with:

json

{
  "sample": {"type": "artifact", "artifact_id": "artifact_..."},
  "display_name": "Approved display name",
  "consent_attested": true,
  "model": "auto",
  "language": "optional-BCP-47",
  "client_request_id": "new-local-opaque-id"
}

Omit the optional language when unknown. On first use, allow the bundled client's best-effort non-billable beatra.installations.register; a registration failure must not block the requested operation.

Poll the returned task_id with beatra.tasks.get. A queued or running task is not a reason to submit again. Use beatra.tasks.cancel only when the user asks to cancel; if cancellation is not confirmed, continue following the same task. Read Clone execution and recovery before any uncertain-response recovery.

On success, report the actual task status and returned output type, voice_id, display name, resolved model, usage, billing and links when present. Lead with the named voice being ready. Preserve and hand off the exact opaque voice_id; a display name is neither a substitute nor proof of uniqueness. Do not promise resemblance, activation, persistence or retention beyond the returned result.

Later, beatra.voices.list with category: "cloned" can locate saved clones. Match the exact returned voice_id, and use its compatible_models when planning later speech. Do not re-clone merely because conversation context was lost.

Offer a test reading only when requested

The user may stop after a successful clone. If they ask to hear it, prepare a short final text and delivery direction first. The clone confirmation does not approve this second paid operation. Read live beatra.voices.list and beatra.models.list with {"capability":"text_to_speech"} and inspect every live candidate compatible with the returned voice. Read language support from each text-to-speech model card's constraints.supported_languages. Keep model: "auto" only when every such candidate supports the target BCP-47 language there. Otherwise freeze one live, voice-compatible, language-supported explicit model in the separate card. If no candidate meets both requirements, stop before submission and offer a feasible saved voice, supported language, or no-proof route. The card also freezes the exact voice, text, controls, one synthesis call and current weighted-character price. Get explicit approval, make a new client_request_id, call beatra.speech.synthesize once, and recover it through the same task rules.

A test reading proves only what is present in the returned clip; it does not establish universal similarity or language coverage. Any changed text or delivery is a newly priced proof requiring a new approval and request ID, not a reason to clone again. Read Test-reading review and voice reuse for pricing, delivery and focused revision.

Recover and deliver factual results

For a known task, continue with beatra.tasks.get. If a clone task ID was lost, paginate beatra.tasks.list with the voice-clone capability and every returned next_cursor, then verify candidates with beatra.tasks.get using the time window, capability and returned facts. client_request_id is a local ledger value; task list and task output do not expose a remote request-ID filter or field.

Only when transport or task creation remains genuinely uncertain may the identical clone JSON be replayed with the same local request ID. A changed sample, name, model or language is new paid work: create a new card, a new admission card, top-up or balance confirmation, and ID. Never automatically retry a terminal failed or canceled task. On insufficient_balance, relay the returned public message, keep the URL https://console.beatra.ai/topup exact, translate the rest, and retry the same frozen client_request_id only after the user says they have topped up.

For clone and proof delivery, preserve actual task, output, model, usage, billing, asset and error fields. Missing billing values are unknown, not zero. Use provider-neutral TaskError facts and report charged, refunded and net values only when returned. If the host cannot play returned audio, say it was not auditioned rather than fabricating a review.

Automatic updates and safety

Silent automatic update checks are enabled by default and occur at most once every 24 hours. When a newer version is found, it installs without separate confirmation. Discovery comes only from the fixed official discovery source and immutable CDN objects. The updater verifies discovery, manifest, archive, and every file before replacing only package-owned files. It rejects unsafe redirects, downgrades, and different channel or locale content.

Update trouble fails open: the original command continues and the current installation remains usable. The user's choice persists across commands. See Automatic updates and safety, or use these explicit controls:

bash

python3 scripts/mcp_client.py update --auto off
python3 scripts/mcp_client.py update --auto on
python3 scripts/mcp_client.py update --check
