TCVoiceAI brings context-aware, two-way voice translation to Mac calls. It routes translated speech through a virtual mic and speaker, so only one side needs the app. Optional History adds bilingual transcripts, CSV export, and custom AI output.
Hi Product Hunt,
I built TCVoiceAI around one practical requirement: only one side of a bilingual call should need translation software.
The user selects a real microphone and speakers in TCVoiceAI, then chooses TCVoiceAI Mic and TCVoiceAI Speaker inside a compatible calling app. Their partner joins normally. TCVoiceAI handles both audio directions from the Mac running the app.
The current release includes:
- **Translated voice:** original speech is replaced by translated speech in both directions.
- **Original audio:** both real voices stay live while TCVoiceAI records and translates bilingual History without spoken translation.
- **Editable conversation context:** add names, terminology, goals, and tone before or during the call.
- **Optional local History:** review the bilingual transcript and export it as CSV. History is required only in Original audio mode.
- **Custom AI conversation output:** retrieve a detail, answer a question, create a recap, draft an email, build a plan, or request another focused result from saved History.
With matching Apple speech recognition and voice support installed, the current app can show up to 41 locale choices across 31 language families.
A few limitations are worth stating clearly:
- The current release is macOS 14+; Windows is still on the roadmap.
- The calling app must let users select and use both microphone and speaker/output devices.
- Google sign-in is required for account, plan, and quota management.
- Translated speech uses a macOS system voice. TCVoiceAI does not clone or imitate the original speaker.
TCVoiceAI uses Apple Speech Recognition on macOS and local macOS speech synthesis. Translation and requested AI output go through the authenticated server API. The server is designed not to retain audio, transcripts, translations, context, prompts, or generated output after a request completes. History is stored locally only when enabled or required by the selected mode.
A free plan is available, with paid monthly plans for higher usage.
I would especially appreciate feedback on three things:
1. Is the difference between Translated voice and Original audio clear?
2. Does the virtual mic/speaker setup make sense on the first read?
3. Which calling app would you want to test first?
Thank you for taking a look.
Would love a way to save custom presets for different languages or accents. Right now I have to tweak the same settings every time I switch from Japanese business calls to Spanish with my family. A simple dropdown to save and recall configurations would save a lot of friction and make repeat sessions feel instant.
Would love a way to set per-contact language preferences so it defaults to the right pair without picking each call.
honestly this looks really useful for international calls, one thing i'd love is the ability to save custom vocabulary or company specific terms so the translation doesnt butcher industry jargon. that would basically make it perfect for my work meetings
