Solution details

In the following demo, we take a look at COVID data and utilize Google’s Speech-to-Text to convert spoken queries into text, setting the stage for a sophisticated data processing workflow. Confluent Cloud’s FlinkAI is specifically utilized to manage calls to Google’s remote inference engine, Gemini, providing efficient and timely processing of SQL queries that were generated from user inputs. This integration within Confluent’s microservices architecture, facilitated by Apache Kafka for real-time data streaming, delivers highly integrated communication and data flow between services. Then, once the data has been retrieved and processed, Gemini summarizes the findings into clear, insightful summaries that are then converted back into natural-sounding speech using Google’s text-to-speech. This robust system, combining Google’s AI capabilities with the specialized function of FlinkAI within Confluent Cloud, is a streamlined approach to delivering fast, accurate, and accessible data-driven insights through intuitive voice commands. This solution not only demonstrates the power of voice and AI integration but also opens up new possibilities for making data-driven insights more accessible to everyone.

How it works:

  1. Voice input: Users interact with a user-friendly voice-enabled interface, articulating their data queries in natural language, such as requesting, “Give me all COVID-19 cases in France in 2021.”

  2. Speech-to-text: Google Speech-to-Text service converts the spoken input into text.

  3. SQL query formation: The text is processed by Gemini to generate an SQL query.

  4. Query execution: The SQL query is executed to fetch the relevant data.

  5. Data summarization: Gemini then summarizes the retrieved data into a concise format.

  6. Text-to-speech: A text-to-speech service converts the summarized text back into natural-sounding speech, which is delivered to the user.

The diagram above shows the overall flow from the user – in natural language – to the AI models and back to the user.

The solution implements the following features:

  • Natural language interface: Users can interact with data using simple, intuitive language, eliminating the need for SQL expertise.

  • Automated query optimization: Using Gemini, Vertex AI leverages its knowledge of data structures and query patterns to generate efficient queries, optimizing performance.

  • Real-time data pipelines: Confluent’s streaming capabilities provide insights with minimal latency, enabling proactive decision-making.

  • Scalability and security: The solution leverages the scalability and security of Google Cloud, ensuring data integrity and compliance (with healthcare regulations).

Let’s take a deeper look at the various components.

1. Speech to Text
The initial phase of our interactive data processing system begins with converting speech to text. Utilizing a KStream application, the solution handles audio inputs where each audio file is processed to extract textual queries. This process involves the AudioProcessor class which, upon receiving an audio file, leverages Google’s Speech-to-Text API to perform accurate and fast speech recognition. Once the audio is processed, the resulting text is encapsulated as an SQLRequest, which contains both the query and session information. This SQLRequest is then forwarded to another topic within our streaming architecture, setting the stage for subsequent SQL generation and data retrieval steps. This transition from audio to text helps ensure that user queries are quickly and accurately converted into actionable database queries, ready for deeper analysis and response generation.

2. Human query to SQL
A standout feature of our demo is the sqlgenerator model, which turns spoken queries into precise SQL commands. This model’s capability hinges on its sophisticated prompt system, designed to handle complex natural language inputs. The prompt details the database schema, guiding the AI to generate SQL queries that are accurate and contextually aware. For example, when a user asks for the total number of COVID-19 tests and first-dose vaccinations for each country in the latest week, the model constructs a query based on an intricate understanding of database structures and relationships, as described in the prompt. This involves parsing and translating diverse data types and table relationships into a cohesive SQL command. Additionally, it outputs a comprehensive JSON description that elucidates the query’s purpose and the data schema it impacts. This intricate prompt design underscores our innovative approach, enabling complex database queries through straightforward voice commands.

3. Query execution
Following the generation of the SQL query by the sqlgenerator model, the subsequent step is its execution, which retrieves the desired data from the databases. Once the data is obtained, the system formats the results into a markdown table. This structuring is crucial as it prepares the data for further processing, tailoring it for readability and further analysis. The formatted table is then processed by another call to the Gemini inference engine, which creates a concise, human-readable summary that can be presented verbally.

4. Table summarization
Building upon the data retrieved and organized into a markdown table, the system calls the “sqlsummary” model, powered by FlinkAI. This model is tasked with generating an easily understandable summary of the table’s data, tailored for audio delivery. It uses a sophisticated prompt mechanism, crucial for directing the AI’s text-generation capabilities. The prompt specifies that the summary should not only recite the data but also provide a coherent narrative about its context, trends, and significant points such as highs and lows.

5. Text-to-speech
The final stage in the data processing pipeline is the text-to-speech conversion, where the summarized text generated by the system is transformed into audible speech. This is accomplished using a KStream application, which takes the prepared text summaries and processes them through a text-to-speech service. This service is configured to deliver high-quality audio output that captures the essence of the data in a clear and engaging manner. The application helps ensure that the speech output is free of any formatting remnants from the text summary, for a clean and professional listening experience. Once the conversion is complete, the audio is then pushed to another topic within the system, to make it accessible for further use.
