eidosSpeech Product Update (March 2026): New APIs, CPU-Only Hardening, and Safer Defaults

We just completed a major implementation pass across NEW_FEATURES.md with a production-first approach: deliver practical capability now, keep existing logic stable, and avoid risky breaking changes.

What Shipped in This Update

Priority 1 and 2 Core Features

• Queue visibility and request flow improvements.
• Webhook-ready async processing flow.
• Audio format conversion and post-processing options.
• Background music mixing support.
• SRT to speech endpoint and subtitle workflow support.
• Translate then synthesize endpoint.

Priority 3, 4, and 5 in Production-Safe MVP Form

• Voice clone job flow API.
• Team and collaboration API foundation.
• Integration registry and template endpoints.
• Billing and plan model foundation.
• Developer experience additions: status page, roadmap page, changelog, and SDK starter packages.

New API Modules Added

The API surface now includes dedicated modules for analytics, teams, voice clone, integrations, developer resources, and expanded TTS workflows.

/api/v1/analytics
/api/v1/teams
/api/v1/voice/clone
/api/v1/integrations
/api/v1/developer/sdk
/api/v1/tts/translate
/api/v1/tts/from-srt
/api/v1/tts/batch

CPU-Only VPS Hardening (4 Core / 6 GB)

For teams running without GPU, this release includes conservative defaults designed to reduce contention and keep latency predictable under load.

• EIDOS_MAX_CONCURRENT=2 to reduce queue collapse on small CPU nodes.
• MAX_HEAVY_OPERATIONS=2 to protect script/multi-segment workloads.
• EIDOS_FFMPEG_THREADS=1 to avoid runaway ffmpeg CPU spikes.
• Lower queue timeout and tighter payload guards for background music and SRT inputs.
• Cache warming disabled by default for lean startup behavior.

Safer Rollout for Non-Monetized Deployments

Not every deployment is ready to sell credits yet. We added a hard toggle so monetization logic can stay out of the request path until you explicitly enable it.

EIDOS_MONETIZATION_ENABLED=false

• Billing routes are excluded when monetization is off.
• PAYG credit deduction checks are skipped.
• payg plan is normalized to free in auth context when disabled.

Backward Compatibility and Safety Notes

• Existing production endpoints remain available.
• New features were added as extensions, not replacements.
• The rollout was verified with compile checks, unit tests, and smoke scripts before release.

What Is Still MVP (Not Full Enterprise Yet)

• Voice cloning is currently a job simulation pipeline, not full GPU model training.
• Team feature does not yet include full shared custom voice libraries and advanced quota policy engine.
• Integration ecosystem is currently API-level registry/template, not full marketplace runtime.
• Official SDK coverage is currently Python and Node starter scope.
