Outstanding Speech Annotation Service

Access the best speech annotation services for Machine Learning and AI projects

What Is Speech Annotation?

Speech annotation is a process of categorizing and labeling sounds for Machine Learning and AI projects. It is essential to turn audio data into a format that machines can understand and learn from. Whether you are interested in speech recognition in AI, the creation of chatbots, or the design of self-driving systems, a credible speech recognition service is a must.


Speech labeling is used in a multitude of industries, from Healthcare and Robotics to Retail. If you want to create an accurate and user-friendly voice-activated system, you need to collect and label huge amounts of data beforehand.

This is where speech annotation services come in place. We offer the full range of services when it comes to voice data services – from collection to categorization. Our team is ready to help you achieve new business objectives and bring the most sophisticated AI system to life.

Industries and Uses of Speech Annotation


Speech data transcription and labeling are widely used in robotics. They help create text-to-speech modules and recognize surrounding objects and environmental changes.


Self-driving cars are no longer a work of fiction. Voice annotation services ensure training of voice-activated systems and virtual assistants that make it possible.


AL and Machine Learning solutions provide more security for private and corporate areas with Automatic Speech Recognition. Audio annotation helps distinguish various sounds and identify potential threats.


In agriculture, IoT and embedded systems with AI allow increasing efficiency. They detect various sounds and movements to give real-time data and respond to changing conditions immediately.


Retail uses speech annotation in a multitude of applications from smart chatbots on eCommerce websites to virtual assistants and embedded systems.


ASR, chatbots, and virtual assistants are quite spread in the entertainment industry. Speech annotation can help design more exciting experiences and applications for users.


Speech annotation services are the foundation of embedded medical systems, surgical robots, and optimization solutions for medical institutions. Such algorithms provide better experiences for patients and professionals.

Speech Annotation Services We Provide

We offer a full range of services from voice data collection to sound annotation and speech to text translation. Our services include:

Speech Data Collection

classification ai

We offer access to various professionals, native speakers, and linguists to model and collect appropriate audio data for your project. Speech data collection allows sourcing specific samples for your requirements for a speech and language annotator to work with in voice-activated systems and algorithms. 

Audio Annotation

data annotation services

We offer provide precise and high-quality labeling of audio annotation services, including speech, sound events, and acoustic scenes for ML.

Multi-Label Annotation

music ai

This process involves the identification and labeling of overlapping sounds. It is particularly important to urban environments and audio recording with multiple different sources of sound. An expert audio annotator can perform binary labeling, one-stage multi-labeling, or two-stage multi-labeling.

Language Transcription


Our language transcription services include verbatim transcription (every word is transcribed as it is in the recording) and labeling that gives more context (identification of a speaker or time stamps for particular markers).

Multilingual Audio Data Services

sound ai

We offer speech recognition in AI systems for multiple languages.

Speech Annotation

artificial intelligence

Investigation and annotation of audio recordings for AI and Machine Learning. Includes provision of metadata for all types of sounds and recognition of each word.

Speech and Audio Data Classification

data classification

This service allows classifying audio data according to your needs from topics to dialects. The experts can classify the speaker’s intent, sound quality, background noises, or any other category you need for your project.

Speech-To-Text Transcription


It is an integral part of NLP – a process of transcription of every word and sound. It includes punctuation and proper labeling of each word/sound.

Types of Speech Classification We Can Help With


Music Classification

This type is used to categorize sounds according to instruments, genres, rhythms, etc. Often, such data is used for entertainment, smart music recommendations, or better organization of multimedia libraries.

Group (69)

Acoustic Data Classification

This type of speech classification identifies where exactly the sample was recorded. This means labeling various environments like schools, public spaces, cafes, homes, etc. Such data is used for various sound libraries and different monitoring systems.

Group (71)

Environmental Sound Classification

Here sound annotation involves the identification and classification of sounds specific to a particular environment. For example, some sounds are common in big cities, others often appear in playgrounds, hospitals, or farmlands. This type is used for monitoring algorithms and security solutions. It can be used for agriculture IoT systems, for example, to monitor and respond to changing environments. Or it can help security algorithms correctly detect uncommon sounds to recognize potential threats.

Group (70)

Natural Language Utterance Classification

This type of voice recognition AI service focuses on various speech specifics like dialects, patterns, or semantics. It is important to teach algorithms to correctly recognize voice commands and signals from people with different speech patterns or various geographical locations. It is useful for virtual assistants, chatbots, or embedded systems.
