Upload an existing audio file or record speech directly in your browser. Our AI-powered speech recognition engine delivers accurate text with speaker labels, timestamps, and smart punctuation. Export as TXT, SRT, VTT, PDF, DOCX, or CSV. Free credits — no credit card needed.
Speech recognition has moved far beyond simple voice typing. Modern AI speech-to-text engines understand context, handle multiple speakers, and maintain accuracy across noisy environments and technical vocabulary. 1bit.ai leverages advanced Whisper-based models to deliver enterprise-grade speech recognition directly in your browser. Whether you are processing recorded interviews, converting dictation files, or transcribing multilingual presentations, our engine decodes spoken language into structured, searchable text with punctuation and speaker-aware formatting.
1bit.ai's speech recognition pipeline combines dynamic noise suppression, language detection across 100+ languages, and context-aware punctuation to produce publication-ready transcripts. Our AI identifies speaker changes automatically, filters conversational filler, and handles domain-specific terminology—from legal dictation to medical case notes. Unlike basic speech-to-text tools, we provide frame-accurate timestamps and export in six professional formats including subtitle-ready SRT/VTT and document formats like PDF and DOCX.
Legal & Medical Dictation: Convert voice recordings of case files, patient notes, and depositions into precise text with strict data privacy and HIPAA-compatible processing.
Executive Communication: Transcribe board meetings, strategy sessions, and quarterly calls into structured minutes and action items automatically.
Academic Research: Record and transcribe interviews, field notes, and focus groups across multiple languages for qualitative analysis.
Accessibility Compliance: Generate accurate text alternatives for audio content to meet WCAG and ADA accessibility standards.
With AI technology, you can quickly turn your audio and video files into text in just a few minutes. It supports 98 languages and a range of formats including MP3, MP4, WAV, M4A, and more.

Pro tips for converting Speech audio to text with maximum accuracy and efficiency
Enunciate without over-pronouncing. Modern AI works best with natural speech patterns, not robotic dictation. Pause briefly between sentences for better punctuation detection.
Even a $30 USB microphone dramatically outperforms laptop built-in mics. Position it 4-6 inches from your mouth and slightly off-axis to reduce plosives ("P" and "B" sounds).
Record in a quiet room away from HVAC vents, refrigerators, and computer fans. Soft furnishings (curtains, rugs, upholstered furniture) reduce echo and improve accuracy significantly.
When using jargon or technical vocabulary, provide brief context in your speech: "using TensorFlow—that's T-E-N-S-O-R-F-L-O-W—for machine learning." This helps AI models correctly identify specialized terms.

Get answers to common questions about Speech transcription and speech to text conversion
Yes. We offer free credits when you register so you can test real-time and file-based transcription, speaker labels, and exports before choosing a plan.
Our models achieve up to 99% accuracy for clear audio with standard accents. Accuracy depends on audio quality, speaker accent, background noise, and technical vocabulary. Most professional use cases see 95-98% accuracy without post-editing.
We support over 100 languages including English, Spanish, Chinese (Mandarin/Cantonese), French, German, Japanese, Arabic, Hindi, Portuguese, Russian, and many more. Our AI also handles code-switching (mixing languages) in bilingual conversations.
Yes, our speaker diarization (speaker separation) works automatically on multi-speaker recordings. We can distinguish and label up to 10+ speakers in a conversation, though accuracy is highest with 2-4 distinct voices.
Yes. Export as SRT, VTT, TXT, Word, PDF, DOCX, or CSV (with or without timestamps). Use timestamps for subtitles or structured text for documentation and search.
Yes, our models are trained on diverse global datasets including various English accents (British, Australian, Indian, African), Spanish dialects (Latin American, Castilian), and regional variations of other major languages.
