To help you understand what's going on, I would recommend running it on your machine (only takes a couple of minutes to get working if you have a Google Cloud service account). In a Nutshell, I want to make sure that when the streaming limit is exceeded and a new request is made, the timestamps returned by Google for that new request are adjusted accurately. These timestamps are accurate for the first request but are off by ~4 seconds in the second request and ~9 seconds in the third request. The timestamp you see printed next to each transcribed response (the 'corrected_time' in the code) is the timestamp for the end of the transcribed line, not the beginning. The timestamps provided by Google are pretty accurate but the issue is that when I exceed the streaming limit (4 minutes) and a new request is made, the timestamped transcript returned by Google's API from the new request is off by as much as 5 seconds or more.īelow is an example of the output when I adjust the streaming limit to 10 seconds (so a new request to Google's Speech-to-Text API begins every 10 seconds). I've adapted their Python infinite streaming example for my purposes (see below for my code). Thankfully, Google provides its own code examples for how to make successive requests to their Speech-to-Text API in a way that mimics endless streaming speech recognition. Google's Speech-to-Text API has a limit of 4 minutes for streaming requests but I want users to be able to run their mic's for as long as 30 minutes if they so choose. The transcription model uses machine learning technology similar to the technology used in YouTube’s video captioning.The web app I'm building relies on real-time transcription of a user's voice along with timestamps for when each word begins and ends. Google’s video transcription model is suited for indexing or subtitling a video or content with multi speakers. The application is capable of adding subtitles in real-time to streaming content. With Google Speech-to-Text, users can transcribe both audio and video content and include captions to help improve audience reach and customer experience. Users can enable voice control or commands like “Turn the volume up,” or do voice search using phrases like “What is the temperature in Paris?’ Such ability can be combined with Google Speech-to-Text API to deliver voice-activated services in IoT applications. Users can then perform analytics on their conversation data, allowing them to gain insights into the interactions and customers. This voice recognition software enables users to empower their customer service system by utilizing the Interactive Voice Response or IVR and agent conversation to their call centers. The main benefits of using Google Cloud Speech-to-Text are further discussed below. Google Cloud Speech-to-Text is a powerful tool that provides state-of-the-art accuracy in a speech to text transcription. The main benefits of Google Cloud Speech-to-Text are improved customer service, implementing voice commands, and transcribing multimedia content. The Google Speech-to-Text API supports over 80 languages. Google Speech-to-text can process audio directly streamed from the user’s microphone or from a pre-recorded audio file, and give real-time transcription result. The speech-to-text API uses a machine learning that is trained to recognize specific audio files from a particular source, thereby improving transcription results. Users can choose from a list of trained models: video, phone call, command, and search, or default. The application can convert spoken numbers into specific addresses, currencies, years, and more. The Cloud Speech-to-Text API allows users to customize speech recognition to allow transcribing domain-specific terms and uncommon words through hints. With Cloud Speech-to-Text, users can transcribe their content with accurate captions, provide an enhanced customer experience through voice commands, and gain customer interaction insights. Google Cloud Speech-to-Text is a cloud-based speech to text transcription tool that uses Google's AI-technology-powered API.
