+pretty_name: The Expresso Dataset
+---
+
+# Info about this dataset
+This is the improvised conversational subset of Expresso, machine segmented and transcribed with turn metadata preserved.
+
+Models used:
+
+- [Silero VAD](https://github.com/snakers4/silero-vad): initial segmentation of audio files
+- [Parakeet TDT 0.6B V2](https://huggingface.co/nvidia/parakeet-tdt-0.6b-v2): transcription of each segment
+
+An 80Hz highpass filter was applied to the source audio prior to segmentation to reduce incidence of the recording environment's low frequency noise.
+
+In total, 26.07 hours of audio remains, as 25091 conversational turns. Some transcription errors are to be expected.

+# The Expresso Dataset
+[[paper]](https://arxiv.org/abs/2308.05725) [[demo samples]](https://speechbot.github.io/expresso/) [[Original repository]](https://github.com/facebookresearch/textlesslib/tree/main/examples/expresso/dataset)
+
+
+## Introduction
+The Expresso dataset is a high-quality (48kHz) expressive speech dataset that includes both expressively rendered read speech (8 styles, in mono wav format) and improvised dialogues (26 styles, in stereo wav format). The dataset includes 4 speakers (2 males, 2 females), and totals 40 hours (11h read, 30h improvised). The transcriptions of the read speech are also provided.
+
+You can listen to samples from the Expresso Dataset at [this website](https://speechbot.github.io/expresso/).
+
+
+### Conversational Speech
+The `conversational` config contains all improvised conversational speech as segmented 48KHz mono WAV.
+
+
+## Data Statistics
+Here are the statistics of Expresso’s expressive styles:

+----------------------------------------------------------------
+*singing is the only improvised style that is not in dialogue format.
+
+
+## Audio Quality
+The audio was recorded in a professional recording studio with minimal background noise at 48kHz/24bit. The files for read speech and singing are in a mono wav format; and for the dialog section in stereo (one channel per actor), where the original flow of turn-taking is preserved.
