Teach Your AI to Listen and Speak with the World
Our Audio and Speech Annotation Services convert raw audio streams into labeled, intelligible data for AI with high-accuracy transcripts and annotations for speech recognition, voice biometrics, and audio analytics.
Comprehensive Audio Services
We provide high-accuracy transcripts and annotations for speech recognition, voice biometrics, and audio analytics.
If you're building voice-enabled applications or analyzing spoken content, our services give you the clean, annotated audio data you need for success. Audio annotation goes beyond basic transcription – it's about capturing the richness of sound in a structured way for machine learning.
Audio Transcription
We transcribe audio recordings into text with extremely high accuracy. This includes proper handling of umms, pauses, slang, and context-specific terminology. Transcripts can be verbatim or cleaned as per project needs. We work with a range of audio: phone call recordings, interviews, dictations, voice assistant queries, etc.
Timestamping & Segmentation
We provide timestamps for words or segments, splitting transcripts by time intervals or when speakers change. This is crucial for training automatic speech recognition (ASR) systems that align audio with text. For example, each spoken sentence or phrase can be time-tagged for precise alignment with the original audio.
Speaker Diarization
"Who spoke when" – we label different speakers in multi-speaker audio. In call center data or multi-person podcasts, we annotate Speaker 1 vs Speaker 2, etc., throughout the transcript. This trains AI models to separate voices and is invaluable for meeting transcription or call analytics to understand which participant said what.
Phonetic & Pronunciation
For speech research and text-to-speech, we meticulously annotate phonemes, pronunciation variations, and even prosody (intonation, stress) markers. This specialized service supports clients developing voice synthesis or accent recognition technologies, enabling more natural-sounding synthetic voices and better language models.
Sound Annotation
Not all useful audio info is spoken words. We tag non-speech sounds in audio when needed (e.g., [laughter], [applause], [door closing]) and classify audio clips (e.g., "music", "speech", "noise"). For smart home audio datasets, we mark events like dog barking or doorbell ringing to train comprehensive sound detection models.
Audio Enhancement
Our audio enhancement service transforms low-quality recordings into clear, usable data. We apply advanced noise reduction, acoustic balancing, and signal processing to improve challenging audio sources. This service is particularly valuable for field recordings, archival content, and audio captured in noisy environments.
Our Technology & Approach
Our team leverages professional transcription platforms and follows industry best practices for audio labeling. We excel at handling various audio qualities – including noisy backgrounds, multiple overlapping voices, and challenging acoustic environments – using sophisticated manual cleanup and audio enhancement tools to improve transcription accuracy. Every project benefits from our multi-stage quality control process to ensure the highest quality outputs.
Audio Annotation Applications & Industries
Wherever there is sound or speech, our annotation services add value by enabling AI systems to better understand and process audio content.
Voice Assistants & ASR Systems
Companies developing AI like Alexa, Siri, or custom voice assistants need massive amounts of transcribed audio to train ASR models. We've contributed to projects involving thousands of hours of voice recordings, covering different accents, languages, and acoustic conditions. Our precise transcriptions (with proper punctuation and casing as required) help voice recognition models achieve higher accuracy in understanding user commands.
Call Centers & Customer Service
Many enterprises analyze phone calls for insights or QA. We transcribe call center audio and label speaker turns, enabling analytics on who said what, sentiment detection in calls, or automated call summaries. With contact center AI adoption rising, having quality transcripts is foundational for training those AI (like for detecting customer sentiment or compliance in calls).
Media & Entertainment
For video content, podcasts, or TV/radio, our audio annotation helps create captions/subtitles and metadata. For instance, transcribing a series of podcasts and tagging segments by topic can help make the content searchable or feed a recommendation engine. Media companies also use annotated audio to train algorithms for content moderation (detecting spoken profanities, etc.).
Automotive (In-car voice)
Modern vehicles often have voice command systems. We annotate in-car speech data (which might include background road noise) to help improve these systems. Also, as hands-free interfaces become standard, car manufacturers collect voice data that we can label to improve wake-word detection and command recognition in the car environment.
Research & Academic
Academics working on speech or linguistics, companies doing sentiment analysis from audio (tone of voice), or biometric identification from voice (speaker identification) all need annotated datasets. We have even labeled data for clinical research, e.g., annotating audio of patients' speech for signs of cognitive impairment (where pauses or mispronunciations are significant).
Healthcare & Medical
The healthcare industry relies on accurate audio annotation for patient records, medical dictation, and telehealth interactions. We provide precise transcription and annotation of medical terminology, ensuring compliance with HIPAA regulations. Our specialized medical annotation team helps develop AI systems for diagnostics, doctor-patient communication analysis, and voice-based health monitoring applications.
Why Choose YPAI for Audio Annotation?
From transcription to sentiment analysis, we deliver precision-labeled audio data that powers superior speech recognition models and voice-enabled AI applications.
Excellence
Expert Transcribers
Our pool of transcribers and audio annotators are highly trained (many with experience in transcription for legal or medical fields, where precision is vital). They are skilled at understanding different accents and dialects in English and other languages. We also use multiple passes – one person transcribes, another reviews – to ensure accuracy exceeding 99%, even on challenging audio.
Noise Handling & Accuracy
Dealing with noisy audio or crosstalk is a reality. We employ specialized audio enhancement techniques and provide guidelines to handle uncertain parts (e.g. marking [inaudible] with timestamps for any portions truly indiscernible, so nothing is just guessed). Our commitment is to deliver transcripts you can trust for model training – no garbled or incorrect text that would confuse your AI.
Language Coverage
Need Spanish, French, or other languages? We can annotate audio in over 100 languages through our global network of linguists. Each language's audio is handled by native speakers to capture nuances. For bilingual scenarios (e.g., code-switching between languages in one clip), we have processes to accurately reflect that in the annotation.
Customized Annotation Tags
If your project needs specific notations (like marking domain-specific terms, or tagging sections of a call as "small talk" vs "problem resolution"), we'll incorporate that. We create annotation schemas for audio that can include tags for sentiment, call stage, or acoustic conditions if needed. Our flexibility ensures the labeled data is maximally useful for your use case.
Data Security & Privacy
Audio data often contains personal conversations or sensitive info. We handle such data with extreme care – secure storage, encrypted transfer, and controlled access. For projects like doctors' dictations or financial calls, we ensure compliance with relevant regulations (HIPAA, GDPR, etc.) during the annotation process. YPAI's ethical approach means your audio data stays confidential and secure.
With YPAI's Audio Annotation, your AI will not only hear but truly understand. We provide the ears and insight for your models – from transcribing words to interpreting meaning behind them.
