Audio
Text-zu-Sprache, Sprache-zu-Text, Musik, Sound-Effekte, Voice-Changer, Dubbing und Voice-Cloning — ein API-Key, alle Provider.
Eine einzige Audio-Oberfläche deckt text-to-speech, transcription, Musik, Soundeffekte, dubbing, Voice-Changing und Voice-Cloning ab. Die Kern-endpoints sind OpenAI-kompatibel, während reichhaltigere Extras — voice settings, speaker diarization, dubbing — überall dort akzeptiert werden, wo der Upstream-Provider sie unterstützt.
Liste zuerst die verfügbaren voices auf; von dir erstellte cloned voices erscheinen in derselben Liste und werden auf dieselbe Weise verwendet.
Endpoints in this section: /v1/audio/speech, /music, /sound-effects, /transcriptions, /audio-isolation, /voice-changer, /dubbing, /voices, plus /v1/voices/* for cloning.
Text-zu-Sprache
Synthetisiere Sprache aus Text. Liefert rohe Audio-Bytes mit dem passenden Content-Type (z.B. audio/mpeg). PCM- und µ-Law-Formate enthalten einen WAV-Header damit sie in jedem Browser abspielbar sind.

}Die Antwort folgt der nativen Struktur des Upstream-Providers (ElevenLabs Scribe), nicht der von OpenAI Whisper: Tokens kommen als flaches words[]-Array zurück (jedes mit einem type von word/spacing und einem logprob), nicht als segments[]. Die Dauer ist audio_duration_secs, und language_code ist ISO-639-3 (z. B. eng, deu). Die speaker_id pro Wort ist nur vorhanden, wenn Sie diarize=true übergeben.
Audio-Isolation

Klone eine Stimme aus kurzen Audio-Samples und nutze sie auf jedem Speech-Endpoint. Voice-Cloning erfordert explizite Einwilligung — hol den aktuellen Consent-Text, hashe ihn und übergib den Hash zusammen mit deinen Samples.
1. Fetch consent text
https://api.airforce/v1/voices/consent-text{
"text": "I confirm that the voice samples I am uploading are either my own voice or a voice I have explicit permission to clone…",
"hash": "9f4b0c8d2e…"
}2. Create the clone
https://api.airforce/v1/voices/clone| Parameter | Type | Required | Description |
|---|---|---|---|
| name | string | Required | Public voice name shown in the library. |
| description | string | Optional | Optional free-text description. |
| consent_hash | string | Required | SHA-256 of the consent paragraph. Fetch the current text via GET /v1/voices/consent-text and pass its hash field. |
| files | binary | Required | 1–25 audio samples. Repeat the form field per file. Total ≤ 200 MB. 30 s – 3 min per clip works best. |

}Hinweis zu den Feldnamen: Die Create-Antwort gibt die neue Stimme als voice_id zurück, während GET /v1/voices/library Klone unter provider_voice_id auflistet. Beide enthalten denselben Bezeichner — den Wert, den Sie als voice übergeben.

4. Update / delete
https://api.airforce/v1/voices/clone/:idhttps://api.airforce/v1/voices/clone/:idPATCH accepts name and description in a JSON body. DELETE removes the voice both locally and at the upstream provider.
Hinweise
- Audio-Antworten werden als rohe Bytes mit dem passenden
Content-Typezurückgegeben. PCM- / µ-law-Formate werden in einen minimalen WAV-Header verpackt, sodass sie unverändert im Browser abspielbar sind. - Multipart-Endpoints (Transkriptionen, Isolation, Voice-Changer, Dubbing, Cloning) akzeptieren bis zu 200 MB pro Request.
- Voice-IDs funktionieren providerübergreifend: Eine geklonte ElevenLabs-Stimme kann direkt an
/v1/audio/voice-changerübergeben werden. - Die Kosten werden pro Zeichen (TTS), pro Sekunde (Musik / SFX / Dubbing / Voice-Changer) oder pro Audiominute (Transkription) abgerechnet und von Ihrem Guthaben abgezogen. Audio-Endpoints senden keinen
X-Cost-Cents-Response-Header — verfolgen Sie Ihre Ausgaben im Usage-Log Ihres Dashboards.
