Ok, please ignore, I think I found the problem now. The code was not super clear about the issue, it is now:

  "error": {
    "code": 400,
    "message": "Voice name Phoebe is not supported. Allowed voice names are: achernar, achird, algenib, algieba, alnilam, aoede, autonoe, callirrhoe, charon, despina, enceladus, erinome, fenrir, gacrux, iapetus, kore, laomedeia, leda, orus, puck, pulcherrima, rasalgethi, sadachbia, sadaltager, schedar, sulafat, umbriel, vindemiatrix, zephyr, zubenelgenubi",
    "status": "INVALID_ARGUMENT"
  }
