Connect Cloud Inference Backends
Cloud TTS is useful for trials, cross-device use, or setups that do not deploy local models. "Free" usually means free tiers, trial quotas, gifted credits, or limited-time campaigns. Quotas and model availability can change; rely on the provider console.
General Steps
- Create an account and API key on the cloud service.
- Open Providers in Neiroha and click +.
- Select the matching adapter.
- Fill
Base URL,API Key, and model name when required. - Click Fetch All to fetch models and voices.
- Enable the provider.
- Click Health Check.
- Create a character in Voice Bank and run Quick Test with one short sentence.
Cloud Entry Points
| Service | Neiroha Adapter | Why Try It | Details |
|---|---|---|---|
| MiMo | OpenAI Chat Completions TTS | One key can access TTS, VoiceDesign, and VoiceClone-style models; useful for Chinese and Chinese-English tests. | MiMo TTS |
| Google Gemini TTS | Google Gemini TTS | AI Studio API key; official docs list free-tier limits for Gemini 2.5 Flash Preview TTS. | Gemini TTS |
| Azure Speech | Azure Speech Service | Azure F0 provides a monthly Neural TTS character quota and stable voice lists. | Azure Speech |
Free Quota Usage
| Workflow | Recommendation |
|---|---|
| Quick TTS | Generate one sentence at a time to confirm character binding. |
| Dialogue TTS | Manually generate 2 to 3 lines before clicking generate all. |
| Phase TTS | Split 3 to 5 segments first to verify long-text style and cost. |
| Novel Reader | Keep prefetch low to avoid spending quota immediately. |
| Video Dubbing | Test a short subtitle section before generating all cues. |
Provider Rate Limits
Cloud failures are often rate-limit failures rather than configuration errors. Set these fields in the provider:
| Field | Purpose |
|---|---|
| Max concurrency | Controls simultaneous TTS requests. |
| RPM | Requests per minute; useful for services like Gemini. |
| TPM | Tokens per minute; useful for token-limited or token-billed services. |
| RPD | Requests per day; useful for free tiers. |
For example, set conservative RPM / TPM / RPD values for gemini-2.5-flash-preview-tts, control Azure F0 by character quota and batch size, and use MiMo Token Plan balance and model consumption rules as the source of truth.
