  • Machine Translation: Support for 600+ language pairs.

Real-Time Transcription

Transcribe from any audio source in real-time.
  • The same features as Batch File mode but in real-time and some great additional options.
  • Subtitles: Generate live subtitles in multiple languages – all beautifully formatted and in real-time.
  • Share: Share real-time output events with multiple client applications concurrently from a single audio stream.
  • Partial Transcriptions: Show partial sentences even before a sentence is complete.

Translation and Natural Language Processing (NLP)

Subtitle Optimized Machine Translation

Get more value from voice data with NLP and translation

Make your voice apps smarter. Use Natural Language Processing tools to get more from your data. Easily enable applications to extract context, syntax, parts of speech, key terms, sentiment, meaning, summarize voice content, and even translate your voice content into other languages.

  • Translate each sentence as it is transcribed in about 50 milliseconds.
  • Configure your voice workflows to enrich your voide data with more information.
  • Enable secondary processes to be smarter and more useful by adding intelligent metadata to the voice text.

Output Formats

Convert Voice to a Variety of Output Formats

Language Studio produces voice document to match a wide variety of use cases.

  • Plain Text Transcription: A simple, clean text file containing the words and sentences spoken.
  • Enriched JSON Data: Includes times, speaker information, channel information, start time, end time, refined punctuation, named entities, confidence scores, translations, sentiment and more.
  • Subtitles and Closed Captions: Create well formatted SRT, TTML, DFXP and VTT subtitle and caption files.
    • Format voice data based on custom configuration for basic rules such as minimum and maximum display time, characters per line, lines per subtitle, reading speed, gaps between subtitles, speaker change formatting, etc.
    • Split subtitles and lines using artificial intelligence in natural positions that make the output feel as if a human had structured the subtitle.
  •  Microsoft Office: Merge variables and Voice JSON data into Microsoft Word and Excel custom templates to produce beautiful meeting minutes, interview transcriptions, notes, etc.


Scale to Thousands of Streams and Users

Seamlessly scale to large numbers of concurrent streams.

  • Each audio stream is an independent Docker container.
  • Multiple Docker containers within a single host can be started and stopped as needed.
  • Multiple users/clients can listen to events to the same stream concurrently, saving resouces.
  • Secured stream output can be accessed only with authentication.
  • Compatible with AWS, Google Cloud, Microsoft Azure and other virtual environemnts.

Accurate Punctuation, Sentence Boundaries, Entity Formatting and Locales

A great balance between control and artificial intelligence

There is no one-size-fits-all in voice. There is also no punctuation or boundaries between sentences. Artificial intelligence combined with some user-defined rules ensures that you get voice data as text in the format that you need it.

  • Sentence Boundaries: Use AI to automatically detect sentence boundaries / end of sentence with a spoken voice. 
  • Punctuation: Use AI to insert punctuation such as commas, periods, question marks and exclamation marks. Override the automated punctuation with your own punctuation rules.
  • Local Formatting: Control the local formatting style such as EN-GB, EN-US and produce different spelling and formatting based on a specific Locale.
  • Entity Formatting: Control entity formats by specifying written or spoken form (“one million dollars” vs. “$1 million”).
  • Latency: Flexible and fixed end points in combination with configurable parameters that control the maximum duration before returning data provide an means to balance speed and accuracy.

REST and WebSockets API

Integreate ASR into your Applications

Use the RESTful and WebSockets APIs to power your applications with Language Studio’s artificial intelligence based tools.

APIs include:
  • Voice Transcription / Speech Recognition
  • Voice Language Identification
  • Voice to Document Alignment
  • Machine Translation
  • Sentiment Analysis
  • Term Extraction
  • Text Language Identification
  • Many more Natural Language Processing (NLP) features.

Accuracy and Customization

Autonomous Speech Recognition is leading the way

Autonomous Speech Recognition (ASR) is a new approach to speech recognition development that is delivering unprecedented accuracy and inclusion. ASR uses the latest techniques in artificial intelligence and machine learning, including the introduction of self-supervised learning models, allowing for much larger datasets from a broader set of voices. Previously unutilized voice recordings from thousands of speakers can now be utilized, even those with different accents, age, or genders, reducing bias, and improving inclusion while delivering unprecedented accuracy, control and customization.
  • Accuracy: Unmatched accuracy.  See how we compare against Microsoft, Google and others >>
  • Bias and Coverage: Due to being able to utilize more than 32 times the amount of voice learning data compared to traditional approaches, our ASR engines consistently outperform all the other industry players for gender bias, accent bias, age bias, and handling of background noise. This translates to significantly better inclusion of all voices.
  • Customize your ASR Engine: Take control of your ASR engine and make it your own.  Learn More >>
    • Custom Dictionary / Glossary: Specify up to 1,000 custom dictionary/glossary terms per language to fine tune your ASR engine on specific words.
    • Industry Domain ASR: Select a Pre-Trained Industry Specific ASR Engine. Domains include Automotive, Banking and Finance, E-Discovery, Engineering and Manufacturing, General Purpose, Information Technology, Medicine and Life Sciences, Military Intelligence and Defense, News and Media, Patents and Legal, Politics and Government, Retail and E-Commerce, Subtitles and Dialog, and Travel and Hospitality.
    • Customize your Own Specific Domain: Omniscien offers a full customization service. We can have a customized domain ready for you in hours or days (varies depending on the scope).

Speaker and Chanel Diarization

Automatically Add Speaker and Channel Labels

It is often useful to know not just what was said but also who said it. Language Studio provides four different modes for separating out different speakers in the audio to support different use cases.
Type Description Use Case
Speaker Diarization Aggregates all audio channels into a single stream for processing and picks out unique speakers based on acoustic matching. Used in cases where there are multiple speakers embedded in the same audio recording and it’s required to understand what each unique speaker said.
Channel Diarization Transcribes each audio channel separately and treats each channel as a unique speaker. Used when it’s possible to record each speaker on separate audio channels.
Speaker Change Provides the point in transcription when there is believed to be a new speaker. Used for when you just need to know the speaker has changed usually in a real-time application.
Channel Diarization & Speaker Change Transcribes each audio channel separately and within each channel provides the point when there is believed to be a new speaker. Used when it’s possible to record some speakers on a separate audio channel, but some channels there are multiple speakers.
