Frequently Asked Questions About Notta AI Transcribe 2026
Notta AI Transcribe 2026 is a comprehensive meeting transcription and intelligence platform, and prospective users naturally have questions before committing. This FAQ addresses the most commonly asked questions across three critical areas: language support, speaker identification, and data privacy.
Whether you’re evaluating Notta for personal use or leading an enterprise procurement process, these answers will help you understand the platform’s capabilities and limitations.
Language Support
How many languages does Notta support?
Notta AI Transcribe 2026 supports over 100 languages and dialects for transcription. This includes major business languages such as English, Spanish, French, German, Portuguese, Japanese, Korean, Mandarin Chinese, Arabic, Hindi, and many more.
The language support covers both real-time transcription (live during meetings) and post-meeting processing (uploaded audio and video files).
Does Notta support real-time transcription in all 100+ languages?
Real-time transcription is available for approximately 58 languages at full accuracy. The remaining languages are supported through post-meeting processing, which can take a few minutes after the meeting ends to generate the complete transcript.
The distinction matters for teams that need live captions during the meeting versus those who primarily review transcripts after the fact.
How accurate is Notta for non-English languages?
Accuracy varies by language, but for the top 20 most-used languages, Notta achieves word error rates (WER) comparable to its English performance:
| Language Tier | Example Languages | Approximate WER |
|---|---|---|
| Tier 1 (Highest accuracy) | English, Spanish, French, German, Portuguese, Japanese | 4-6% |
| Tier 2 (High accuracy) | Korean, Mandarin, Italian, Dutch, Polish, Russian | 6-8% |
| Tier 3 (Good accuracy) | Arabic, Hindi, Thai, Vietnamese, Turkish | 8-12% |
| Tier 4 (Functional accuracy) | Less common dialects and regional languages | 12-18% |
These figures assume clear audio quality and standard dialect. Heavily accented speech, regional dialects, or poor audio conditions will increase error rates across all tiers.
Can Notta handle multilingual meetings?
Yes, Notta supports automatic language detection and switching within a single meeting. If participants switch between languages — for example, a meeting conducted primarily in English with occasional Japanese — Notta will detect the language shift and transcribe each segment in the appropriate language.
However, there are limitations:
- Rapid code-switching (alternating languages within a single sentence) is less accurately handled
- Simultaneous multilingual speech (two participants speaking different languages at the same time) may result in errors
- Accuracy is highest when language switches occur at natural conversation boundaries (between speakers or between topics)
Does Notta support custom vocabulary for industry-specific terms?
Yes. Notta allows users to create custom vocabulary lists that improve recognition of:
- Industry-specific terminology (medical, legal, technical)
- Company and product names
- Acronyms and abbreviations
- Proper nouns (client names, project names)
Custom vocabulary is available on Pro plans and above. The system applies vocabulary lists based on the user’s profile or meeting type, so medical terminology doesn’t interfere with engineering meetings.
Can Notta transcribe audio files in addition to live meetings?
Yes. Notta supports transcription of uploaded audio and video files in all 100+ languages. Supported formats include:
- Audio: MP3, WAV, M4A, FLAC, OGG, AAC
- Video: MP4, MOV, AVI, WMV, WebM
File upload transcription is available across all plans, though the free plan limits file duration to 5 minutes. Pro and Business plans support files up to 5 hours in length.
Speaker Identification
How does Notta identify different speakers?
Notta uses a multi-signal speaker identification system that combines several techniques:
- Calendar integration: Before the meeting, Notta pulls participant names from the calendar invite and pre-assigns speaker labels
- Meeting platform metadata: Participant names from Zoom, Google Meet, or Teams are used to map speakers
- Voice embeddings: Notta creates acoustic fingerprints for each speaker’s voice characteristics (pitch, cadence, timbre)
- Temporal modeling: The system tracks speaker changes based on conversational patterns and timing
- Voice profile library: For recurring contacts, Notta stores voice profiles that improve identification over time
How accurate is speaker identification?
Speaker identification accuracy depends on several factors:
| Scenario | Accuracy |
|---|---|
| 2 speakers, clear audio | 97-99% |
| 3-5 speakers, clear audio | 91-95% |
| 6-8 speakers, clear audio | 85-90% |
| 9+ speakers | 80-87% |
| Mixed in-person/remote | 78-85% |
| Similar-sounding speakers | 75-85% |
The most challenging scenario is similar-sounding speakers in a large group — for example, multiple participants of the same gender and age range speaking in similar accents. In these cases, manual correction after the meeting can improve the record.
Does speaker identification improve over time?
Yes. Notta maintains voice profiles that become more accurate with each meeting. After approximately 3-5 meetings with the same participants, the system reaches its highest accuracy level for those speakers.
This learning is:
- Per-user: Each Notta account builds its own voice profile library
- Privacy-respecting: Voice profiles are stored as mathematical embeddings, not raw audio
- Deletable: Users can delete voice profiles at any time through the settings interface
Can I manually correct speaker labels?
Yes. After any meeting, users can reassign speaker labels in the transcript editor. Corrections are applied retroactively to the entire transcript and feed back into the voice profile system, improving future identification for the corrected speaker.
Manual correction takes approximately 2-3 minutes for a typical meeting with occasional misattributions.
Does speaker identification work for phone calls?
Yes, but with reduced accuracy compared to video conferencing platforms. Phone calls present two challenges:
- Lower audio quality: Phone audio is compressed and narrowband, providing fewer acoustic features for speaker modeling
- No participant metadata: Unlike Zoom or Teams, phone calls don’t provide participant names
For phone calls recorded through Notta’s mobile app, accuracy for 2-person calls remains above 90%. For multi-party conference calls, accuracy drops to 80-85%.
How does Notta handle speakers who join late or leave early?
Notta dynamically adjusts its speaker model throughout the meeting. When a new participant joins:
- The system detects a new voice signature not matching existing profiles
- It creates a temporary speaker label (e.g., “Speaker 4”)
- If calendar data associates the timing with a known participant, it auto-assigns the correct name
- If no metadata match is found, the label remains until manually corrected
When a participant leaves, the system removes their voice profile from the active model, improving accuracy for remaining speakers.
Data Privacy and Security
Where does Notta store my data?
Notta stores data in cloud infrastructure with data center locations in:
- United States (default for North American users)
- European Union (available for EU-based organizations)
- Asia Pacific (available for organizations in the region)
Enterprise plan customers can specify data residency requirements, ensuring that all audio, transcripts, and metadata are stored in a specific geographic region. This is critical for organizations subject to GDPR, data sovereignty laws, or industry-specific regulations.
Is my meeting audio stored permanently?
By default, Notta stores meeting audio for the duration specified in your plan settings. Users and administrators can configure data retention policies:
| Setting | Options |
|---|---|
| Audio retention | 30 days, 90 days, 1 year, indefinite, or custom |
| Transcript retention | Independent of audio retention — can be kept longer |
| Automatic deletion | Configurable per meeting type or team |
| Manual deletion | Users can delete individual recordings at any time |
On the free plan, audio is retained for 90 days before automatic deletion. Transcripts are retained indefinitely unless manually deleted.

How does Notta handle recording consent?
Notta provides several mechanisms for recording consent management:
- Bot announcement: When Notta’s meeting bot joins a call, it can be configured to announce that the meeting is being recorded
- Consent prompts: Before transcription begins, participants can be shown a consent notification
- Opt-out mechanism: Individual participants can request that their contributions be excluded from the transcript
- Policy documentation: Notta provides template consent policies that organizations can adapt for their legal requirements
Recording consent requirements vary by jurisdiction. In the United States, laws range from one-party consent (only one participant needs to agree) to all-party consent (every participant must agree), depending on the state. International regulations vary further. Organizations should consult legal counsel to ensure their recording practices comply with applicable laws.
