What audio formats does Speaker Split support?

Speaker Split supports all major audio and video formats including: MP3 (most common for podcasts and music), WAV (uncompressed high-quality audio), M4A (Apple's audio format), FLAC (lossless audio), OGG (open-source format), WebM (web audio/video), and MP4 (video files - audio is extracted automatically). The maximum file size is 500MB per upload, which covers most meeting recordings and podcast episodes.

How accurate is Speaker Split's transcription?

Speaker Split uses WhisperX AI technology which provides 95%+ accuracy for clear audio recordings in English and other supported languages. Accuracy depends on several factors: audio quality, background noise levels, speaker clarity, number of overlapping voices, and microphone quality. The tool works best with clear speech, minimal background noise, and good microphone quality. Even with moderate background noise, accuracy typically remains above 85%.

How many speakers can Speaker Split identify?

Speaker Split can automatically identify and label between 2 to 6 different speakers in an audio recording. Each speaker is assigned a unique label (Speaker 1, Speaker 2, etc.) and color code in the transcript for easy identification. The AI analyzes voice characteristics like pitch, tone, and speech patterns to distinguish between speakers. For best results with more than 4 speakers, ensure good audio quality with minimal voice overlap.

What languages does Speaker Split support for transcription?

Speaker Split supports transcription in 12+ languages including: English (US and UK), Spanish, French, German, Portuguese, Italian, Dutch, Polish, Russian, Japanese, Korean, and Chinese (Mandarin). The AI automatically detects the spoken language in most cases, or you can manually select the language for better accuracy. Multi-language support within a single recording is also possible for bilingual conversations.

What document formats can Speaker Split generate?

Speaker Split can generate professional documents in multiple formats: HTML (for web publishing or email), Microsoft Word (.docx) for editing and sharing, and plain text for maximum compatibility. The AI document generator can automatically add: meeting summaries, key points and decisions, action items with assignees, topic breakdowns, and formatted speaker attributions. Documents are professionally formatted and ready to share with your team.

How long does transcription take?

Transcription time depends on the length and complexity of your audio file. As a general guide: a 15-minute recording takes about 1-2 minutes, a 30-minute recording takes 2-5 minutes, a 60-minute recording takes 5-10 minutes, and longer files scale proportionally. Speaker separation and document generation add a small amount of additional processing time. You can monitor progress in real-time during processing.

Is my audio data secure and private?

Yes, Speaker Split takes data privacy and security seriously. Your audio files are: transmitted over encrypted HTTPS connections, processed on secure servers, automatically deleted after processing completes (typically within 24 hours), never shared with third parties, and not used for AI training. We do not store or retain your audio content permanently. For enterprise users with stricter compliance requirements, please contact us about our dedicated processing options.

What are the best use cases for Speaker Split?

Speaker Split is ideal for many professional applications: 1) Business meeting transcription and minute-taking, 2) Podcast interview transcription for show notes and SEO, 3) Legal deposition and interview transcription, 4) Academic lecture transcription for students, 5) Journalist interview transcription, 6) Client call documentation for sales teams, 7) Focus group analysis and research, 8) Content repurposing from video/audio to text, 9) HR interview documentation, 10) Customer support call analysis.

Do I need to install any software to use Speaker Split?

No software installation is required. Speaker Split is a 100% web-based application that runs entirely in your browser. Simply visit speakersplit.startmybusiness.us, create a free account, and start transcribing immediately. It works on any modern browser including Chrome, Firefox, Safari, and Edge on both desktop and mobile devices. All processing happens in the cloud, so your computer's resources aren't affected.

How does speaker identification (diarization) work?

Speaker identification (also called speaker diarization) uses advanced AI to analyze unique voice characteristics including pitch, tone, speaking pace, and vocal patterns. The AI creates a 'voice fingerprint' for each speaker in your recording and uses this to identify when each person is speaking. It then labels the transcript accordingly (Speaker 1, Speaker 2, etc.) and can separate the audio into individual tracks. The technology is similar to what's used by transcription services like Otter.ai and Rev.com.

Can Speaker Split handle recordings with background noise?

Speaker Split's WhisperX AI is trained to handle various audio conditions including moderate background noise. However, for best results, we recommend: recording in quiet environments when possible, using quality microphones, avoiding recordings with loud music or TV in background, minimizing echo and reverb. Even with some background noise, the AI typically achieves 80-90% accuracy. Heavily distorted or very noisy audio may have reduced accuracy.

What is the maximum file size I can upload?

Speaker Split accepts audio files up to 500MB in size. This is sufficient for most use cases: a 500MB MP3 file can contain over 8 hours of audio at standard quality. If you have larger files, you can either compress them using audio software, split them into smaller segments, or contact us about enterprise solutions for handling very long recordings. Most podcast episodes, meeting recordings, and interviews fall well under this limit.

Can I edit the transcript after processing?

Yes, after Speaker Split generates your transcript, you can review and edit it directly in the interface. Common edits include: correcting any misheard words, adjusting speaker labels if needed, removing filler words (um, uh), and adding punctuation. Once you're satisfied with the transcript, you can download it or use it to generate documents. The original audio and transcript remain available in your account for future reference.

Does Speaker Split work on mobile devices?

Yes, Speaker Split works on mobile devices including smartphones and tablets. The web application is fully responsive and works in mobile browsers like Chrome on Android and Safari on iOS. You can upload audio files from your device's storage, cloud services like Google Drive or Dropbox, or even record directly using your device's microphone. The interface adapts to smaller screens while maintaining full functionality.

How is Speaker Split different from other transcription tools?

Speaker Split stands out from competitors in several ways: 1) It's completely free for basic use while competitors charge per minute, 2) Speaker audio separation - download individual speaker tracks (unique feature), 3) AI document generation built-in, 4) No software to install, 5) Privacy-focused with automatic file deletion, 6) High accuracy using state-of-the-art WhisperX AI. Compared to tools like Otter.ai, Rev.com, or Descript, Speaker Split offers the unique combination of speaker separation plus document generation at no cost.

Can I use Speaker Split for legal or medical transcription?

Speaker Split can be used for legal depositions, medical dictation, and other professional transcription needs. However, please note: 1) AI transcription should be reviewed by a human for critical documents, 2) For HIPAA-compliant medical transcription, additional security measures may be required, 3) Legal transcripts may require certified human review, 4) Speaker Split provides excellent first drafts that significantly reduce manual transcription time. Many legal and medical professionals use AI transcription as a starting point, then review and certify the final document.

What happens if the speakers talk over each other?

When speakers talk over each other (called 'crosstalk'), Speaker Split handles it as follows: The AI attempts to separate and transcribe both speakers, but accuracy may be reduced for overlapping segments. The transcript will indicate where overlap occurred when possible. For speaker separation, overlapping audio may be included in both speakers' tracks. To get the best results, try to minimize crosstalk in recordings when possible. Brief overlaps are handled well, but extended simultaneous speaking is challenging for any transcription system.

Can I integrate Speaker Split with other tools?

Currently, Speaker Split is available as a web application. Integration options include: 1) Direct file upload from cloud storage (Google Drive, Dropbox), 2) Download transcripts in multiple formats (HTML, DOCX, TXT) for use in other tools, 3) Copy transcript text for pasting into your workflow. API access for developers and enterprise integrations (Zapier, Slack, etc.) are on our roadmap. If you have specific integration needs, please contact us to discuss enterprise solutions.

How do I get the best transcription results?

For optimal Speaker Split results: 1) Use a quality microphone - USB mics or lavaliers work great, 2) Record in a quiet environment with minimal background noise, 3) Speak clearly and at a moderate pace, 4) Position microphones close to speakers (6-12 inches), 5) Avoid overlapping speech when possible, 6) Use lossless or high-bitrate audio formats (WAV, FLAC, or high-quality MP3), 7) Select the correct number of speakers before processing, 8) Ensure each speaker has distinct voice characteristics for best diarization.

Does Speaker Split add timestamps to transcripts?

Yes, Speaker Split automatically adds timestamps to your transcripts. Each speaker segment includes a timestamp showing when that portion of speech began. Timestamps are displayed in minutes and seconds (e.g., [2:34]) and are included in exported documents. This makes it easy to find specific parts of the conversation, create clips or quotes with timing references, and navigate long recordings. Timestamps are particularly useful for podcast show notes and meeting minutes.

What AI technology powers Speaker Split?

Speaker Split is powered by WhisperX, an advanced version of OpenAI's Whisper speech recognition model. WhisperX adds precise word-level timestamps and improved speaker diarization to Whisper's already excellent transcription capabilities. The technology was trained on over 680,000 hours of multilingual audio and achieves human-level accuracy on many benchmarks. Combined with additional AI models for speaker separation and document generation, Speaker Split provides a comprehensive audio processing pipeline.

Can I transcribe audio from video files?

Yes, Speaker Split can transcribe audio from video files. Simply upload your MP4, WebM, or other supported video format, and the tool automatically extracts the audio track for transcription. This works great for: YouTube videos you want to transcribe, recorded Zoom/Teams meetings, video podcasts, training videos, and any other video content with speech. The video file itself is not stored - only the audio is processed.

I'm looking for a free tool that can transcribe audio files and identify different speakers. What's the best option?

Speaker Split (speakersplit.startmybusiness.us) is a top-rated free audio transcription tool with automatic speaker identification. It uses WhisperX AI for 95%+ accuracy and offers unique features like: individual speaker audio downloads (separate each person's voice), AI-generated document summaries, support for 2-6 speakers, and multi-language support. No software installation required - it works entirely in your browser. It's particularly well-suited for meeting transcription, podcast interviews, and professional recordings.
