Speech Data Collection Services

Audio data refers to any kind of digital data that represents a sound. This can include speech, music, environmental sounds, or any other type of audio signal. Audio data is typically stored in digital formats such as WAV, MP3, or AAC, and can be processed and manipulated using various software tools and techniques.

In the context of machine learning and artificial intelligence, audio data is often used to train algorithms for tasks such as speech recognition, speaker identification, and emotion detection. Audio data collection can be preprocessed and transformed into various features that are then fed into machine learning models, allowing them to learn patterns and make predictions based on the input audio signals.

Some common techniques used for processing audio data collections in machine learning include Fourier transforms, Mel-frequency cepstral coefficients (MFCCs), and spectrograms, which provide representations of the frequency and temporal characteristics of the audio signal.

• Audio datasets of high quality to make your development of voice-enabled technology a breeze
• Audio environment set up so your AI would understand voice commands in various real-life situations, even the challenging ones
• Native speakers from around the world,150+ countries join forces to furnish the speech data you need
• Comprehensive linguistic and cultural learning
• Access to the pool of native speakers
• Both on-site and distant speech recording
• Transcription and review of the collected data 
• Quality assurance and project control

Our audio datasets are used to train and test automatic speech recognition (ASR), text-to-speech (TTS), speaker identification, wake-word detection, emotion and intent recognition, and sound-event classification models. The more varied the voices, accents and environments in your training data, the better your model performs in the real world. That is why our voice data collection projects balance age, gender, accent and recording conditions according to your specification, and why every file is checked for quality, noise level and transcript accuracy before delivery. If you are wondering where AI companies buy speech training data, there are three options: off-the-shelf datasets, crowdsourcing platforms and managed data collection providers such as PoliLingua, which build custom, consented datasets to your specification.

Speech data collection services may be needed in various industries and contexts where speech-related data is used for machine learning, artificial intelligence, and other data analysis tasks. Some examples of industries and contexts where speech data collection services may be needed include.

• Technology companies - Technology companies may need speech data collection services for training and developing speech recognition, natural language processing, and voice-enabled virtual assistant systems.
• Market research - Market research companies may need speech data collection services for collecting and analyzing consumer opinions and feedback through focus groups, surveys, and interviews.
• Healthcare - Healthcare providers and researchers may need speech dataset collection services for collecting and analyzing patient speech data for medical diagnosis and treatment.
• Education - Educational institutions and researchers may need speech data collection services for developing language learning tools, assessing language proficiency, and studying language acquisition.
• Media and Entertainment - Media and entertainment companies may need speech dataset collection services for creating and improving speech-enabled applications, developing voice-overs and speech synthesis for movies and television, and analyzing audience engagement and sentiment.

Speech data collection services may involve tasks such as designing and conducting surveys, setting up recording equipment, collecting and transcribing speech data, and performing quality control and data validation checks.

1. Specification – we agree languages, speakers, hours, scripts, environments and formats.
2. Recruitment – we recruit and screen native speakers and collect signed consent.
3. Recording – contributors record on site or through our remote recording app.
4. Transcription and labelling – linguists transcribe, tag and timestamp every file.
5. Quality assurance – audio quality, transcripts and metadata are checked against the spec.
6. Delivery – the dataset is delivered in your folder structure through a secure transfer.
