There’s no feature documented to auto-generate a playable preview/sample for voices you create (including IVC via API). The voice object may include samples and an optional preview_url, but these exist only if you or the system have provided/assigned them. (elevenlabs.io)
ElevenLabs does not offer a way to “preview” a voice without actually generating audio (which consumes credits). So you won’t get free/automatic previews just by creating the voice. (help.elevenlabs.io)
If you plan to share a Professional Voice Clone in the Voice Library, you must first generate a short clip (70–150 characters) and choose it as the custom preview; otherwise there’s nothing to play. (help.elevenlabs.io)
What you can do
Generate a short TTS clip for each voice (e.g., 1–2 sentences) via API: POST /v1/text-to-speech/:voice_id. This is the documented way to produce audio you can play; it will consume credits. (elevenlabs.io)
Programmatically verify whether a voice currently has anything to play by calling GET /v1/voices/:voice_id and checking samples[] and preview_url. If empty/null, no preview will play until you generate audio. (elevenlabs.io)
For Professional Voice Clones, you can also attach additional sample audio via the PVC samples API if needed. (elevenlabs.io)

So, to get a playable sample in the dashboard, generate a short TTS clip for each clone (or, for PVC you intend to share, set a custom preview from a 70–150 character generation). They won’t be created automatically. (elevenlabs.io)
