![]() However, the service currently only supports English and Spanish. NET, Go, Java, JavaScript, PHP, Python and Ruby.Īmazon’s offering automatically recognizes multiple speakers and can provide a timestamp, which makes it easier for users to locate the audio or video segment associated with a specific sentence. ![]() Additionally, Amazon has a variety of software development kits (SDKs) to improve the use of this transcription service, which supports. Amazon TranscribeĪmazon Transcribe enables developers to submit audio - via a standard REST interface - in several formats, including WAV, MP3, MP4 and FLAC, as well as from any device. Currently, the service supports 29 languages, as well as WAV and Opus audio formats. In some cases, client apps use the WebSocket protocol to improve performance. In addition, Microsoft developed several client libraries to improve integration with various apps written in C#, Java, JavaScript and Objective-C. However, Microsoft charges an additional fee for the use of these custom models.ĭevelopers can also code applications to deliver recognition results in real time this could enable an application to give users feedback to speak more clearly or to pause when their words are not being properly recognized.ĭevelopers can access the Azure Speech to Text API from any app using a REST API. A custom language model, for example, could improve transcription accuracy for a regional dialect, while a custom acoustic model could improve accuracy for a headset used in a call center. One of the strengths of Microsoft Azure Speech to Text is its support for custom speech and acoustic models, which enables developers to customize speech recognition for a particular environment. Here’s a closer look at these speech-to-text services from AWS, Microsoft and Google and some of the key features they offer. They also, however, have some important differences. The biggest benefit of these services, which the cloud providers deliver as APIs, is their ability to integrate with the broader platform of tools and services on which they run. But they continue to evolve with new capabilities, such as enhanced and automated punctuation, and will likely continue to improve as providers develop more accurate speech processing models. These speech-to-text services - which are part of the AI portfolios public cloud providers continue to build out - are still in their early days. Development teams can weave these capabilities into timesaving apps for a range of uses, including call center analytics, video indexing services, web conference indexing and business transcription workflows. Amazon Transcribe, Microsoft Azure Speech to Text and Google Cloud Speech-to-Text enable developers to create dictation applications that can automatically generate transcriptions for audio files, as well as captions for video files.
