Convo supports English, Spanish, French, German, Portuguese, Italian, and Polish. Transcription can auto-detect the language or be fixed to one (which is more accurate; Polish calls need Polish selected), and summaries have their own language setting: Auto to match the call, or any of the seven. Both live in Settings under Preferences.
Convo works in seven languages: English, Spanish, French, German, Portuguese, Italian, and Polish. Transcription and summaries have separate language settings, so you can sell in one language and report in another.
Transcription language
In Settings → Preferences, the transcription language controls how Convo hears your calls:
- Auto-detect: Convo figures out the language, useful when your calls switch between languages. It covers every language except Polish
- A specific language: English, Spanish, French, German, Portuguese, Italian, or Polish. For Polish calls, select Polish
Accuracy tip: if your calls are consistently in one language, pick it explicitly. Auto-detect uses a multilingual model that trades some accuracy for flexibility; a fixed language uses the more accurate dedicated model.
Summary language
Summaries have their own setting, also in Settings → Preferences:
- Auto: the summary follows the language of the call
- A fixed language: every summary in the language you pick, regardless of the call's language, for example Spanish-language calls with English summaries for the CRM and the team
Getting names and jargon right
Preferences also includes a custom dictionary where you can add your own terms: product names, company names, industry jargon. Convo uses it to transcribe those words correctly instead of guessing at spellings.
