Overview

The “Audio to Utterance - Data Table” Tool leverages state-of-the-art speech recognition algorithms to transcribe audio files accurately. It goes beyond simple transcription and provides the ability to focus on all speakers or just the interviewees. Furthermore, you can specify target themes and topics. Final results are saved as a structured data table. This feature allows you to organize and analyze your audio data in a more efficient and systematic manner. With its powerful capabilities and user-friendly design, it is the perfect solution for audio analysis.
Keep in mind that the resulting dataset can be used as knowledge for a next step AI analysis.

Key Features

  1. Accurate Transcription: The “Audio to Utterance - data table” Tool utilizes advanced AI techniques to transcribe audio files accurately. It analyzes the audio content, identifies speech patterns, and converts them into text with high precision. This feature ensures that you receive reliable and accurate transcriptions, allowing you to focus on extracting valuable insights from your audio data.
When working with video files, to avoid upload issues, extract the audio before upload and directly work with the audio content.
  1. Speaker Identification: The tool can identify different speakers in the audio recording and attribute the transcribed utterances to each speaker. This speaker identification feature is particularly useful in interviews, panel discussions, or any audio recording with multiple participants. It allows you to differentiate between speakers and analyze their contributions separately.
To emphasize on interviewees, make sure to trim your audio files in a way that the first heard voice is the interviewer/moderator. This way, you can use the "Exclude the first speaker" option.
  1. Time Stamps: The tool provides time stamps for each transcribed utterance, indicating the exact timing of when it was spoken in the audio recording. These time stamps enable you to align the transcribed text with the original audio, facilitating accurate referencing and analysis.
  2. Customizable Target Themes: You have the flexibility to focus on all or a certain subset of discussed themes/topics. This customization ensures that the Tool accurately identifies utterances relevant to the target analysis.
  3. Organized Results: The Tool provides the results as a data table saved on your account. This table is accessible under the Data page. Columns are
    • text: utterances
    • speaker: speaker labels
    • start and end time of each utterance
    • categories: a list of most relevant categories from the specified list
You can easily navigate through the data table or extract the results as a CSV file. This organized format saves you time and effort in manually reviewing and analyzing your audio data. Furthermore, you can use this theme-focused dataset of utterances as knowledge for more AI analysis.

How to use the Tool

Locate the Tool in the template page and click on Use template. You can use the Tool as is or clone it. Using the “Audio to Utterance - Data table” Tool is a simple and straightforward process. Follow these steps to transcribe and analyze your audio files:
  • Upload Audio File: Select the audio file you want to transcribe and analyze. The Tool supports various file formats, including MP3, WAV, MP4, and more. Ensure that the audio file is accessible and available for upload.
  • Specify Output Dataset: Type a name for the output dataset that will contain the transcribed text and marked sections. This dataset will be created to store the results of the analysis.
  • Specify Source File Name (Optional): If desired, you can provide a name for the source file. This name will be used to identify the audio file within the output dataset.
  • Keep/Exclude the First Speaker: If you wish to focus on responses provided by the interviewees, make sure the moderator is the first person heard in the audio and select Exclude the First Speaker.
To emphasize on interviewees, make sure to trim your audio files in a way that the first heard voice is the interviewer/moderator. This way, you can use the "Exclude the first speaker" option.
  • Target Themes/Categories: Apart from filtering by speaker, there are options for filtering utterances by theme/category. Select Filter by themes/topics under “Target data” and enter the list if target categories to filter out non-relevant utterances. This way, the Tool will analyze the transcribed text and identify utterances matching these topics.
You can build a Tool which receives a transcription as input and suggests applicable categories. Note that the existing Tool is designed for analyzing survey responses and some modifications might be needed to fine-tune it for interview analysis.
The Tool will transcribe the audio, identify utterances matching the configured criteria.
  • View Results: The Tool will provide you with the transcribed text and extracted utterances in the output dataset. Go to Data and refresh the page. You can explore the transcribed text, review the extracted utterances and export the table content into a CSV file.
Apply audio Tools to multiple files at the same time (bulk-run):
  1. Upload your audio files together in a data table
  2. Add an enrichment/bulk-run using the desired audio Tool (**Do this step right after uploading your files and activate the bulk run. The URL in the table to access the original file are temporary **)
  3. Select the file_url field from the table to access the audio file for the bulk-run (Note that the URLs expires in maximum 72 hours from upload)
  4. When source file name is required use source_file_name field from the table

​
What can be next?

  1. Apply the above analysis to all your recordings (bulk run) and have one table containing all important and insightful utterances
  2. Use the resulting table as knowledge in a Tool similar to Focused summarization and quote extraction.
