Audio Data Sets for Speech Recognition Training – Application Examples

Voice Recordings – Creation of Audio Data Sets

Text to Speech

Each human voice and speech pattern is unique. They differ in intonation, speed, and pronunciation, as well as in elements of dialect. These factors complicate the development of automated speech recognition systems.

Audio Data Sets Voice recording

A good speech recognition system must be trained with a vast number of high-quality speech recordings provided by various people in order to cover the range of human language nuances and, as such, be capable of performing the correct actions.

Our crowd provides you with voice recordings and data on

  • how people phrase and pronounce instructions to voice assistants,
  • how people respond and comment of speech recognition systems,
  • how people pronounce and emphasize predefined sentences and
  • how clearly sentences are comprehended when they are said by people of divers origins and with different background noises.
  • Large quantities of audio files in a short space of time
  • Thousands of varied, authentic voice patterns
  • A considerable number of languages and dialects
  • Recordings in varied environments
  • Speech recording and immediate data transfer via the Clickworker app
  • Various data formats – wav, mp3 / mono, stereo, 8 and 16 Bit
  • Quality check

Transcription of Audio Data Sets

Speech to Text

High-performance speech recognition systems that convert authentic language into text require extensive man-made training data for machine learning.

Audio Data Sets - Transcription

With the help of our international crowd, we provide voice recordings and also transcribe audio files in numerous languages. The transcriptions are only processed by qualified Clickworkers, carried out precisely and checked before being accepted.

These high-quality training data enable your speech recognition system to continue learning, and to achieve optimal results.

  • Large quantities of transcriptions in a short space of time
  • Numerous languages
  • Correct punctuation
  • Comments about the audio files
  • Various data formats
  • Quality check

Classification of Audio Data Sets

Speech recognition systems that are meant to learn how to communicate and perform actions must be able to correctly interpret, assess and place the spoken word in the appropriate context.

Classification of Audio Data Sets

Our Clickworkers can filter out this information from audio files and make them available as training data for your speech recognition system.

Analyses can include, for instance, the emotional tonality as well as the subject matter of the spoken text in addition to the quality of the audio file (with regard to clear sound, articulation and correctness of the voice commands).

The analysis of this data provides your system with first-rate audio data sets as well as more detailed content-related information about the audio files – for optimized use in human interaction.

  • Fast-quality filtering for large quantities of audio files
  • High-quality analysis of the content with human intellect
  • Numerous languages
  • Quality check
