Better undestanding

Making speech more intelligible and removing background noise.

Original
Enhanced

Research with our clients shows that voices enhanced with Alta Voce get to engage with more customers than in their normal, unprocessed audio conditions.

Try it in Python

import os
os.environ["VOIMOOO_LICENSE_ID"] = "AAAA-BBBB-CCCC-DDDD"

import pyvoimooo
import pysndfile

wav, fs, enc = pysndfile.sndio.read("yourfile.wav")
syn = pyvoimooo.pvoccombo(
  wav,
  fs, 
  efx_inteligibility_scaling=0.5
)
pyvoimooo.writewav("yourfile_intellegible.wav", fs, syn)

It's how you say it

Varying expressivity

Martin (French)

Martin more dynamic

Martin even more dynamic

Our technology can gradually shape the expressivity in a voice, e.g. to make it more dynamic.


Varying prosody inflections

Federica (TTS, Italian)

Buongiorno 1

Buongiorno 2

Buongiorno 3

It is common knowledge that how we say something is more important than what we say. Our research proved it, and our technology allows to find the expressive features conveying the desired intention. For example, listen to Federica’s voice more trustworthy.
