Package naming

Package naming#

Every application package name encodes the dimensions that make it specific: which model it contains, how large it is, which variant, the language, the target platform, and (for TTS) the voice. Reading the name tells you whether a package fits your use case and device before you download it.

Anatomy of a package name#

An ASR package:

niagara-38m-live.en-linux-x86_64
   │      │    │  │  │
   │      │    │  │  └── platform: Linux, x86-64
   │      │    │  └───── language: English
   │      │    └──────── variant: live (streaming, low-latency)
   │      └───────────── size: ~38 million parameters
   └──────────────────── model family: Niagara (ASR)

A TTS package additionally carries a voice:

nith-5m-live.en-m1-linux-x86_64
  │   │    │ │  │  │
  │   │    │ │  │  └── platform: Linux, x86-64
  │   │    │ │  └───── voice: m1 (male, voice 1)
  │   │    │ └──────── language: English
  │   │    └────────── variant: live (streaming, low-latency)
  │   └─────────────── size: ~5 million parameters
  └─────────────────── model family: Nith (TTS)

Fields#

Field

Meaning

Example values

Family

The model, which implies ASR or TTS

niagara (ASR), nith (TTS)

Size

38m (~38M), 5m (~5M)

Variant

Shared library name#

The shared library inside a package mirrors the family, size, and variant, so niagara-38m-live ships libniagara_38m_live.so and nith-5m-live ships libnith_5m_live.so. You pass the path to this .so when constructing an Asr or Tts object.
