The best AI note taker for multilingual sales calls

What makes a sales call "multilingual" for an AI note taker?

"Multilingual" gets used for three different needs, and vendors blur them because the language count on their pricing page sounds bigger. Separate them before you shortlist anything.

A tool that transcribes 100 languages can still fail the second and third needs. That is why our top pick for mixed-language calls is Notta, whose bilingual mode is built specifically for the second row of this table, with transcript translation into 42 languages covering the third.

Which AI note takers handle two languages in the same call?

This is the question vendor language counts hide, and it is the one that matters most for code-switched sales calls.

Notta offers the most direct answer: bilingual transcription with 23 languages to choose from, where you pick the two languages of the call and both are transcribed. In manual bilingual testing, its bilingual live transcription scored 5/5. Bilingual mode includes 4 free uses a month, then costs $9 a month on an annual plan or $15 month-to-month.

Sembly AI supports mixed-language meetings on every plan, including Basic at $10 a month billed annually — the cheapest way to get mixed-language handling.

Fireflies.ai puts a Multi-language Mode on its Business plan ($19 a month billed annually), alongside its conversation intelligence features.

tl;dv handles multiple languages in one meeting using the Whisper model, but only on Business and Enterprise plans.

Otter.ai supports language switching between French and English only — useful if that is your pair, limiting otherwise.

For Fathom, MeetGeek and Avoma, mixed-language handling within a single call is not confirmed on their documentation, so test with a real code-switched call before committing.

Which tools cover the most languages for sales calls?

If your calls each stay in a single language and you simply need broad coverage, the raw language count matters more. These figures are vendor claims from their own pages, checked 29 October 2026, and they change often:

Two caveats. First, a bigger number does not mean better: Fireflies itself notes English is primary and other languages are in beta, while Notta's 58 languages pair with a dedicated bilingual mode that most larger lists lack. Second, none of these counts tells you what happens when a speaker switches language mid-sentence — that is the previous question.

Can managers read the notes in English if the call was in another language?

Often yes, but the mechanism differs by tool and by plan.

Gong's AI Translator covers transcripts, summaries and briefs, and translated summaries can be exported to the CRM — the most complete translation story for multi-market revenue teams.

Notta translates completed transcripts into 42 languages, so a call conducted mostly in Spanish can be reviewed in English afterwards. The translation add-on costs $6 a month on an annual plan or $10 monthly, separate from the bilingual add-on.

Avoma translates transcripts and notes on its Organization plan and above ($29 a month annual per recorder seat).

Fathom can translate summaries into six languages on Team Edition.

If your workflow is "local rep runs the call, English-speaking manager reads the notes," check both the translation feature and the plan it sits on before shortlisting.

Do sales coaching features work outside English?

This is where multilingual claims most often fall apart. Gong — the strongest conversation intelligence option on this list — explicitly lists several features as English-only: email labels, red flag alerts, Gong-recommended to-dos and example-based smart trackers. Transcription, translation and summaries work across its 70+ languages, but the coaching layer that justifies its price may not fire on your non-English calls.

The lesson generalises: for any conversation intelligence tool, ask the vendor which specific intelligence features — trackers, scorecards, coaching insights — are verified on the languages your team actually sells in, and get it in writing. A tool that transcribes 100 languages but only coaches in English is a transcription tool for most of your markets. Notta, Sembly and Fireflies trade some coaching depth for broader language handling, which is a reasonable trade if translated notes matter more to your workflow than English-only analytics.

How accurate is AI transcription when speakers switch language?

Code-switching is genuinely hard for speech recognition. A June 2026 benchmark from ServiceNow AI tested seven ASR models on Spanish-, French-, Canadian French- and German-English code-switched speech and found that accuracy penalties vary substantially by model, that errors tend to concentrate on the English portions of the audio, and that Whisper sometimes translates instead of transcribing — writing down a translation rather than what was actually said.

Two limits of that benchmark: it used synthetic (TTS) audio, and it tested ASR engines rather than note-taker products. But it explains why a tool can be accurate in each language separately and still fumble the switch, and why a dedicated bilingual mode — like Notta's, where you declare the pair up front — is more reliable than hoping a single-language model copes. For why overlapping speakers cause their own errors, see our guide to overlapping speech transcription.

What does multilingual support cost per rep?

Prices checked 29 October 2026, per rep unless noted. Watch for add-ons: the sticker price rarely includes the multilingual feature you actually need.

For a rep who regularly runs two-language calls, Notta's Pro plus the bilingual add-on comes to roughly $17 a month on annual billing — less than Fireflies Business and far less than an unpublished enterprise CI contract — while covering the mixed-language case those tools handle partially or not at all.

Our verdict

For sales calls where speakers switch between two languages, Notta is the pick to try first: its bilingual mode covers 23 language pairs, scored 5/5 in manual bilingual live-transcription testing, and costs $9 a month as an add-on on top of a Pro plan at $8.17 a month — with 4 free uses a month to test it on your own calls before paying anything. Add transcript translation into 42 languages and it also solves the "manager reads in English" problem. Choose Gong instead if you run coaching and CRM workflows across many markets and can verify its English-only feature list against your languages; choose Sembly AI if you want the cheapest mixed-language handling on every plan; and choose Fireflies Business if you want conversation intelligence bundled with a Multi-language Mode at a mid-range price.
