Speech to text Model in client reviews using BigQuery ML

Best Speech To Text Models

The integrated speech-to-text feature of BigQuery ML provides an effective means of extracting insightful information from audio data. With this service, audio files like customer review calls are converted from audio to text so they can be analyzed on BigQuery’s powerful data platform. You can uncover consumer sentiment, spot reoccurring product problems, and learn more about your customers’ voices by fusing speech-to-text with BigQuery’s analytics features.

A deeper knowledge of consumer interactions across numerous channels is made possible by BigQuery ML speech-to-text, which converts audio data into actionable insights with potential benefits across sectors.

Moreover, BigQuery ML’s native speech-to-text feature may be used to utilize Gemini 1.0 Pro to obtain more insights and data formatting, including entity extraction and sentiment analysis, for text retrieved from audio recordings. Some application cases and their business worth for particular sectors are listed below:

IndustryUse CasesBusiness Potential
Retail/E-commerceAnalyzing customer call recordings to identify common pain points, product preferences, and overall sentimentImproved product development by addressing issues mentioned in feedback Enhanced customer service through personalization and targeted assistance Enhanced marketing campaigns based on insights discovered in customer calls.
HealthcareTranscribing patient-doctor interactions to automatically populate medical records, summarize diagnoses, and track treatment progressMore streamlined workflows for healthcare providers, reducing administrative burden Comprehensive patient records for better decision-making Potential identification of trends in patient concerns for research and improved care
FinanceAnalyzing earnings calls and shareholder meetings to gauge market sentiment, identify potential risks, and extract key insightsSupport for more informed investment decisions Prompt identification of emerging trends or potential issues Proactive Risk Management strategies
Media & EntertainmentTranscribing podcasts, interviews, and focus groups for content analysis and audience insightsEarlier identification of trending topics and themes for new content creation Understanding audience preferences for program development or advertising Accessibility improvements through automated closed-captioning

By utilizing sophisticated AI functionalities like BigQuery ML, you can leverage all the inherent governance features of BigQuery, including access control passthrough. This allows you to limit insights from client audio files according to row-level security settings on your BigQuery Object Table.

Are you prepared to extract insights from your audio data?

Let’s explore BigQuery’s speech-to-text capabilities:

Speech To Text models

Consider that you have a number of audio recordings of calls you’ve had from customers that are kept in a Google Cloud Storage bucket. These audio recordings can be automatically converted into readable text within BigQuery using the ML.TRANSCRIBE function, which is linked to a pre-trained speech-to-text model hosted on Google’s Vertex AI platform. Consider it as a specialist translator for audio information.

The location of your audio files (in your object table) and the speech-to-text model you want to use are specified to the ML.TRANSCRIBE method. The transcription process is then managed by it, making use of machine learning capabilities, and the text results are sent straight to BigQuery. This facilitates the analysis of corporate data in conjunction with consumer conversations.

Advantages of BigQuery ML’s speech-to-text capabilities:

Efficiency: Compared to manual transcribing, automated transcription saves a great deal of time and money.
Scalability: BigQuery is perfect for companies that receive a lot of customer evaluations since it can manage massive amounts of audio data.
Expense-effectiveness: Uses Google’s speech-to-text algorithms that have already been trained, saving costly third-party solutions.
Actionable Insights: Offers insightful information that may be applied to enhance customer satisfaction and spur company expansion.

Together, let’s navigate the BigQuery procedure:

How to set up:

  • Choose your Google Cloud project, connect a payment account, and enable the required APIs before you begin (all instructions available here).
  • Make a recognizer. A recognizer is optional to construct and stores the speech recognition configuration.
  • Get a service account for the cloud resource connection by creating one; complete instructions are available here.
  • Follow these instructions to grant access to the service account.
  • Using the instructions provided, create a dataset containing the object table and the model.
  • Take a listen and save the audio files to Google Cloud Storage.
  • Here are five audio tracks that you can download.
  • Open Google Cloud Storage and create a bucket and folder inside of it.

Place the downloaded audio tracks in the “Follow-up Ideas” folder:

  • Utilising Gemini 1.0 Pro and BigQuery ML’s ML.generate_text function, take the text retrieved from the audio files and extract desired entity data (e.g., product names, stock prices) and format it in JSON.
  • Measure the sentiment analysis of the captured text using Gemini 1.0 Pro with BigQuery ML, then organize the good and negative sentiments into JSON.
  • Integrate verbatim and sentiment scores from customer feedback with the Customer Lifetime Total Value score or other pertinent customer data to observe the relationship between quantitative and qualitative data.
  • Create embeddings over the text that has been extracted, and then utilize vector search to look for certain information in the audio recordings.

Obtaining client feedback is now simpler than ever in the digital era. But sorting through a tone of audio reviews can be a difficult undertaking. Here’s where BigQuery ML’s speech-to-text functionality shines, providing an effective means of revealing the insightful information concealed in your customers’ audio data.

This is how speech-to-text in BigQuery ML can change customer feedback:

  • Upload your audio review files to Google Cloud Storage for effortless transcription. With the speech-to-text feature of BigQuery ML’s, users can save numerous hours of human labor by having the audio automatically transcribed into text.
  • Unlocking Hidden Gems: Users can take advantage of BigQuery’s robust analytics features once the audio has been translated to text.
  • Assess feedback sentiment, look for reoccurring themes, and group it into categories to learn more about customer satisfaction levels and potential areas for development.
  • Practical insights: Anyone may spot trends and patterns in client feedback by looking at the transcription of the text. In the end, this serves to enhance the client experience by helping them to priorities problems and effectively resolve concerns.
  • Data Preparation: Use a Cloud Storage bucket to upload the sound review files (such as.mp3 or.wav).
  • Speech-to-Text Transcription: To connect to a pre-trained speech-to-text model stored on Vertex AI, use the ML.TRANSCRIBE function in a BigQuery script. This function converts the audio automatically into text and saves it in a BigQuery table.
  • Analysis of Data: Use the data analysis tools that BigQuery comes with to look through the transcribed text.
  • One may: Examine sentiment Determine whether the reviews are neutral, positive, or negative.
  • Take out the terms and phrases: Find out what subjects and themes clients frequently bring up.
  • Sort and classify comments: Sort the reviews according to a particular product, feature, or problem for more focused study.
  • Action and Improvement: In light of your study, take appropriate measures to resolve client complaints, enhance the quality of your offering, and raise total client satisfaction.

In summary

The speech-to-text function of BigQuery ML’s provides a strong and affordable means of extracting the insights from the audio evaluations left by your customers. One may learn more about your consumers and take steps to enhance their experience by turning audio into text and using BigQuery’s analytics features.
