Transcribe an audio file with Universal-1 in Node.js

AssemblyAI has introduced a new speech model called Universal-1, which boasts near-human accuracy in speech-to-text conversion even with accented speech and background noise. The model is also faster than its predecessor, Conformer-2, and supports English, Spanish, French, and German languages. Alongside this release, two new pricing tiers - Best and Nano - have been introduced. The Best tier offers high accuracy for applications where precision is crucial, while the Nano tier provides cost-effective transcription services in 99 different languages. Users can transcribe audio files using Universal-1 and Nano through AssemblyAI's Go SDK by setting up an authenticated client and configuring speech model parameters.
